Chemical Structure
Description
The occurrence of 4-Amino-7-chloro-1,3-dihydrofuro[3,4-c]quinoline-8-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Amino-7-chloro-1,3-dihydrofuro[3,4-c]quinoline-8-carboxylic acid (CAS 2774613-66-8), molecular formula C12H9ClN2O3 and molecular weight 264.66 g/mol, is a CATO reference standard with documented purity and traceability.
4-Amino-7-chloro-1,3-dihydrofuro[3,4-c]quinoline-8-carboxylic acid (C12H9ClN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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).
