1,3-Dimethylurea CAS#96-31-1
1, 3-Dimethylurea is a urea derivative and used as an intermediate in organic synthesis. It is a colorless crystalline powder with little toxicity. It is also used for synthesis of caffeine, pharmachemicals, textile aids, herbicides and other. In the textile processing industry 1,3-dimethylurea is used as intermediate for the production of formaldehyde-free easy-care finishing agents for textiles. In the Swiss Product Register there are 38 products containing 1,3-dimethylurea, among them 17 products intended for consumer use. Product types are e.g. paints and cleaning agents. The content of 1,3-dimethylurea in consumer products is up to 10 % (Swiss Product Register, 2003). Use in cosmetics has been proposed, but there is no information available as to its actual use in such applications.

Product Application Of 1,3-Dimethylurea CAS#96-31-1
N,N′-Dimethylurea can be used:
As a starting material to synthesize N,N′-dimethyl-6-amino uracil.
In combination with β-cyclodextrin derivatives, to form low melting mixtures (LMMs), which can be used as solvents for hydroformylation and Tsuji-Trost reactions.
To synthesize N,N′-disubstituted-4-aryl-3,4-dihydropyrimidinones via Biginelli condensation under solvent-free conditions.
