4-Bromo-6-(difluoromethyl)-5-iodopyridine-3-sulfonamide CAS 1805245-63-9

Description

Compared with other compounds in its class, the molecular weight of 412.98 g/mol gives 4-Bromo-6-(difluoromethyl)-5-iodopyridine-3-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Bromo-6-(difluoromethyl)-5-iodopyridine-3-sulfonamide (CAS 1805245-63-9), a certified reference material (molecular formula C6H4BrF2IN2O2S, MW 412.98 g/mol) for analytical method development and quality control.

The molecular framework of 4-Bromo-6-(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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 4-Bromo-6-(difluoromethyl)-5-iodopyridine-3-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.
