Description
CATO manufactures 4-Fluoro-3-iodopyridine-5-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 4-Fluoro-3-iodopyridine-5-sulfonyl chloride (CAS 1803880-20-7), a certified reference material (molecular formula C5H2ClFINO2S, MW 321.50 g/mol) for analytical method development and quality control.
Structurally, 4-Fluoro-3-iodopyridine-5-sulfonyl chloride (C5H2ClFINO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 321.50 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
