Chemical Structure

2,6-Dichloro-3-(difluoromethoxy)benzenesulfonyl chloride CAS 1803787-63-4 chemical structure

Description

As a certified reference material (CRM), 2,6-Dichloro-3-(difluoromethoxy)benzenesulfonyl 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.

CATO supplies 2,6-Dichloro-3-(difluoromethoxy)benzenesulfonyl chloride (CAS 1803787-63-4), a certified reference material (molecular formula C7H3Cl3F2O3S, MW 311.52 g/mol) for analytical method development and quality control.

Structurally, 2,6-Dichloro-3-(difluoromethoxy)benzenesulfonyl chloride (C7H3Cl3F2O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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 311.52 g/mol, it falls into the moderately-high-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.
