Chemical Structure
Description
The occurrence of 6-Bromo-2-(difluoromethyl)-5-iodopyridine-3-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Bromo-2-(difluoromethyl)-5-iodopyridine-3-sulfonamide (CAS 1805422-83-6), molecular formula C6H4BrF2IN2O2S and molecular weight 412.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-2-(difluoromethyl)-5-iodopyridine-3-sulfonamide (C6H4BrF2IN2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system. 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. 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.
