5-amino-2-chloro-pyridine-3-carboxylic acid (CAS 42959-39-7) is a high-purity analytical reference standard with the molecular formula C6H11ClN2O2 and a molecular weight of 178.62 g/mol.
5-amino-2-chloro-pyridine-3-carboxylic acid (C6H11ClN2O2) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
