General description

4-Amino-2,6-dimethoxypyrimidine is methoxy substituted 4-aminopyrimidine. Molecules of 4-amino-2,6-dimethoxypyrimidine are linked by an N-H.O hydrogen bond and an N-H.N hydrogen bond, forming sheets containing centrosymmetric rings. Photocatalytic degradation of 4-amino-2,6-dimethoxypyrimidine on TiO2 has been reported. Mass spectra of 4-amino-2,6-dimethoxypyrimidine has been studied.

New nitrosopyrimidines were synthesized and evaluated as potential antibacterial agents. Different compounds structurally related with 4,6-bis(alkyl or arylamino)-5-nitrosopyrimidines were evaluated. Some of these nitrosopyrimidines displayed significant antibacterial activity against human pathogenic bacteria. Among them compounds 1c, 2a-c, and 9a-c exhibited
