Chemical Structure
Description
2-(Difluoromethyl)-4-iodopyridine-5-sulfonamide (CAS 1806774-86-6), molecular formula C6H5F2IN2O2S and molecular weight 334.08 g/mol, is a CATO reference standard with documented purity and traceability.
2-(Difluoromethyl)-4-iodopyridine-5-sulfonamide (C6H5F2IN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 2-(Difluoromethyl)-4-iodopyridine-5-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.
