Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 4-(Difluoromethyl)-3-methoxy-5-methylpyridine-2-sulfonyl chloride (CAS 1805151-31-8), a certified reference material (molecular formula C8H8ClF2NO3S, MW 271.67 g/mol) for analytical method development and quality control.

Structurally, 4-(Difluoromethyl)-3-methoxy-5-methylpyridine-2-sulfonyl chloride (C8H8ClF2NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 271.67 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
