Chemical Structure
Description
3-chloro-1,6-naphthyridine-7-carboxylic acid (C9H15ClN2O2) contains an amide group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-chloro-1,6-naphthyridine-7-carboxylic acid (CAS 2250243-66-2), molecular formula C9H15ClN2O2 and molecular weight 218.68 g/mol, is a CATO reference standard with documented purity and traceability.
