4-(Difluoromethyl)-5-iodo-6-methylpyridine-3-sulfonyl chloride CAS 1805267-03-1

Description

As a certified reference material (CRM), 4-(Difluoromethyl)-5-iodo-6-methylpyridine-3-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4-(Difluoromethyl)-5-iodo-6-methylpyridine-3-sulfonyl chloride (CAS 1805267-03-1) is a high-purity analytical reference standard with the molecular formula C7H5ClF2INO2S and a molecular weight of 367.54 g/mol.

The molecular framework of 4-(Difluoromethyl)-5-iodo-6-methylpyridine-3-sulfonyl chloride (C7H5ClF2INO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/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.

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.
