2-(Difluoromethyl)-5-hydroxy-3-iodopyridine-6-sulfonamide CAS 1807071-72-2

Description

The molecular framework of 2-(Difluoromethyl)-5-hydroxy-3-iodopyridine-6-sulfonamide (C6H5F2IN2O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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).

2-(Difluoromethyl)-5-hydroxy-3-iodopyridine-6-sulfonamide (CAS 1807071-72-2) is a high-purity analytical reference standard with the molecular formula C6H5F2IN2O3S and a molecular weight of 350.08 g/mol.

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.
