  • sell 1,3-Dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone; DMPU; N,N'-Dimethyl-N,N'-trimethyleneurea; N,N'-Dimethylpropyleneurea

    DMPU is a versatile aprotic polar solvent for N-alkylation of chiral primary amines, O-alkylation of aldoses and the synthesis of poly (arylene ethers). It is an effective alternative to carcinogenic HMPA, As a highly reactive nucleophile and a co-solvent for the base; high Z-selectivity in enolate formation; DMPU exhibits non-mutagenicity and safety.
