Sodium 3-iodopyridine-2-sulfinate (CAS 2387364-40-9) is a high-purity analytical reference standard with the molecular formula C5H3INO2SNa and a molecular weight of 291.03 g/mol.
The molecular framework of Sodium 3-iodopyridine-2-sulfinate (C5H3INO2SNa) is characterized by a salt form, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Sodium 3-iodopyridine-2-sulfinate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
