3,4-Dichloro-2-(difluoromethoxy)benzenesulfonyl chloride CAS 1805124-22-4

Description

Compared with other compounds in its class, the molecular weight of 311.52 g/mol gives 3,4-Dichloro-2-(difluoromethoxy)benzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Dichloro-2-(difluoromethoxy)benzenesulfonyl chloride (CAS 1805124-22-4) is a high-purity analytical reference standard with the molecular formula C7H3Cl3F2O3S and a molecular weight of 311.52 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 3,4-Dichloro-2-(difluoromethoxy)benzenesulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 3,4-Dichloro-2-(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.
