Beschreibung

Anwendung

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.
