Diethyl 6-methyl-4-oxo-7,8,9,9a-tetrahydro-1H-pyrido[1,2-a]pyrimidine-1,3(4H,6H)-dicarboxylate CAS 33499-13-7

Description

Diethyl 6-methyl-4-oxo-7,8,9,9a-tetrahydro-1H-pyrido[1,2-a]pyrimidine-1,3(4H,6H)-dicarboxylate (C15H22N2O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
