Chemical Structure
Description
Sodium 6-chloropyridine-2-sulfonate (C5H3ClNO3SNa) contains a salt form, an amide group, a sulfone 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.
Sodium 6-chloropyridine-2-sulfonate (CAS 132931-07-8), molecular formula C5H3ClNO3SNa and molecular weight 215.58 g/mol, is a CATO reference standard with documented purity and traceability.
