4-(Difluoromethyl)-2-methylpyridine-3-sulfonyl chloride CAS 1805320-86-8

Description

4-(Difluoromethyl)-2-methylpyridine-3-sulfonyl chloride (CAS 1805320-86-8) is a high-purity analytical reference standard with the molecular formula C7H6ClF2NO2S and a molecular weight of 241.64 g/mol.

Based on its molecular formula C7H6ClF2NO2S, 4-(Difluoromethyl)-2-methylpyridine-3-sulfonyl chloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 241.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
