Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Sodium 5-fluoropyridine-2-sulfinate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Sodium 5-fluoropyridine-2-sulfinate (CAS 2137701-68-7), molecular formula C5H3FNO2SNa and molecular weight 183.13 g/mol, is a CATO reference standard with documented purity and traceability.
