Description

CATO manufactures 4-Chloro-5-(difluoromethyl)-3-iodopyridine-2-sulfonamide 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.

4-Chloro-5-(difluoromethyl)-3-iodopyridine-2-sulfonamide (CAS 1804494-68-5), molecular formula C6H4ClF2IN2O2S and molecular weight 368.53 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H4ClF2IN2O2S, 4-Chloro-5-(difluoromethyl)-3-iodopyridine-2-sulfonamide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
