Chemical Structure
Description
2-Methyl-N-(2-methyl-4-oxoquinazolin-3(4H)-yl)cyclopropanecarboxamide (C14H15N3O2) 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).
