Chemical Structure
Description
ethyl 7-bromo-4-oxo-pyrido[1,2-a]pyrimidine-3-carboxylate (C11H17BrN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
