Dimethylurea (DMU) (IUPAC systematic name: 1,3-Dimethylurea ) is a urea derivative and used as an intermediate in organic synthesis. It is a colorless crystalline powder with little toxicity. 1,3-Dimethylurea is used for synthesis of caffeine, theophylline, pharmachemicals, textile aids, herbicides and others.[2] In the textile processing industry 1,3-dimethylurea is used as intermediate for the production of formaldehyde-free easy-care finishing agents for textiles. The estimated world production of DMU is estimated to be less than 25,000 tons.Nonlinear optical properties of 1,1-dimethylurea (N,N′ dimethylurea), have been evaluated through second-harmonic generation. 1,1-Dimethylurea (N,N-dimethylurea) has been used in the Dowex-50W ion exchange resin-promoted synthesis of N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones. Dimethylurea belongs to the class of organic compounds known as ureas. Ureas are compounds containing two amine groups joined by a carbonyl (C=O) functional group. Dimethylurea is an extremely weak basic (essentially neutral) compound (based on its pKa). Dimethylurea (DMU) (IUPAC systematic name: Dimethylurea ) is a urea derivative and used as an intermediate in organic synthesis. N,N′-Dimethylurea (1,3-Dimethylurea), an alkyl urea derivative,[3] is a nonlinear organic material.[4] It forms needle-shaped crystals. It has been crystallized by using ethylacetate (solvent) and heptane (precipitant) by vapor diffusion technique. Its crystals has one molecule in each asymmetric unit. Molecules in crystal are linked by hydrogen bonds. N,N′-Dimethylurea is the suitable reagent used to investigate the polar structure of its crystals.[1] It may be used in the Dowex-50W ion exchange resin-promoted solvent-free synthesis of N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones. N,N'-DIMETHYLUREA is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NO INDUCE VOMITING. IMMEDIATELY transpor the victim to a hospital. (NTP, 1992). Quantitative on‐line NMR spectroscopy is applied to study equilibria and reaction kinetics of the reaction of formaldehyde with 1,3‐dimethylurea. This reaction system serves as a model system for the much more complex but industrially relevant urea–formaldehyde system. The aim is to study individual reactions and intermediates. The 1,3‐dimethylurea–formaldehyde system undergoes only four reactions and, unlike urea–formaldehyde, does not form polymers. The following reactions are studied in detail: (1) the hydroxymethylation, (2) the formation of hemiformals of the hydroxymethylated intermediate, and (3) two condensation reactions of which the first leads to methylene bridges, the other to ether bridges. NMR spectroscopic chemical shift data of the reacting species are provided for the 1H, 13C, and 15N domains. Equilibrium data of reactions (1), (2), and (3) are determined by quantitative 1H and 13C NMR spectroscopy at molar ratios of formaldehyde to 1,3‐dimethylurea between 1:2 and 16:1 at a pH value of 8.5. Reaction kinetic experiments using an NMR spectrometer coupled to a batch reactor led to a reaction kinetic model parametrized with true species concentrations. The model takes into account reactions (1), (2), and (3). It describes the reaction system well for molar ratios of 1:1, 2:1, and 4:1, temperatures of 303 to 333K, and pH values from 5.0 to 9.5. Dilution experiments with a micro mixer coupled to the NMR spectrometer are conducted to estimate the time to equilibrium of reaction (2) of which the time constant is significantly lower than those of reactions (1) and (3). Dimethylurea is a colorless powder, used as building block for active ingredients or intermediate for formaldehyde-free textile additives.Formaldehyde-free textile additives. Cross linking agent for textiles made of cellulose fibers and their synthetic mixtures. Reagant for the synthesis of active ingredients, such as bronchodilators. In the crystal structure of N,N′-dimethylurea, there is one molecule in the asymmetric unit, but with two halves related by an axis of pseudosymmetry. All nonhydrogen atoms of each molecule lie on a plane. In the crystal the molecules are held together by hydrogen bonds in the direction of the “a” axis. They form parallel rows with the same sense orientation, so that the crystal has a polar structure. Diuron (3-[3,4-dichlorophenyl]-1,1-dimethyl urea) is an herbicide with carcinogenic activity in rats and mice, which have developed respectively urothelial and mammary gland tumors in long-term studies. Accordingly, diuron has been categorized as a “likely human carcinogen” by the U.S. Environmental Protection Agency. Although the carcinogenesis-initiating activity of diuron has been reported in an early initiation-promotion mouse skin study, its genotoxic potential has been disputed. It is necessary to clarify the mode of action through which it has caused rodent neoplasia and verify its relevance to humans. Herein, two experiments were developed to verify the initiating and promoting potentials of diuron in a twenty-three- and a twenty-one-week–long mouse skin carcinogenesis protocol. In one, dimethylsulfoxide (DMSO) was the solvent for the herbicide; in the other, acetone was the alternative solvent in order to verify whether DMSO had inhibitory influence on a potential cutaneous carcinogenic activity. The adopted schedule for the tumor-promoting agent 12-O-tetradecanoylphorbol 13-acetate (TPA) resulted in skin ulcers, which demonstrates the need for careful selection of TPA dose levels and frequency of application in this model. In both studies, diuron did not exert any influence on the skin carcinogenesis process, in contrast with results already reported in the literature.Diuron (3-[3,4-dichlorophenyl]-1,1-dimethyl urea) is a widely used herbicide for weed control in the cultivation of soy, cotton, sugar cane, citrus fruit, wheat, and coffee crops, as well as in non-crop areas such as airport runways, railroads, and oil-pipes. Occupational exposure is the main concern about this herbicide. Agricultural workers frequently neglect safety practices, including the use of personal protective equipment designed to avoid dermal exposure during pesticide mixing or application. Dalian richfortune chemicals offers a wide range of products which includes 1,3-dimethylurea. It belongs to Intermediates category. Uses: the intermediates of synthesis theophylline and caffeine.Contact us for more information. The phase behavior of dioleoylphosphatidylethanolamine in aqueous solutions of urea, N,N'-dimethylurea (DMU), and N,N,N',N'-tetramethylurea (TMU) has been characterized by synchrotron X-ray diffraction and differential scanning calorimetry. All three solutes stabilize the lamellar liquid-crystalline phase at the expense of lamellar-gel phase and inverted hexagonal phase of the phospholipid when present in concentrations up to 3 M. X-ray diffraction data demonstrated that the repeat spacing of DOPE increased with increasing urea concentration, but decreased as the DMU and TMU concentrations increased. The repeat spacing of DOPE in the liquid-crystal phase dispersed in the three solutes is d(urea)>d(DMU)>d(TMU). The molecular mechanisms underlying these observations are discussed in terms of either membrane Hofmeister effect, where urea acts as a water structure breaker, or a direct insertion effect of the amphiphilic DMU and TMU molecules into the lipid head groups in the interfacial region of the phospholipid bilayer.Dimethylurea is a colorless to white powder, with an amine-like odor.1,3-Dimethylurea (DMU) is a solid in the form of white crystals with a faint ammonia-like odor It is soluble in water.
