Chemical Structure
Description
CATO supplies 6-Chloro-5-nitropyridine-3-sulfonyl chloride (CAS 62009-39-6), a certified reference material (molecular formula C5H2Cl2N2O4S, MW 257.05 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution, 6-Chloro-5-nitropyridine-3-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 6-Chloro-5-nitropyridine-3-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.
