2,3-Dichloro-5-(difluoromethoxy)benzenesulfonyl chloride CAS 1804936-65-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Dichloro-5-(difluoromethoxy)benzenesulfonyl chloride.

2,3-Dichloro-5-(difluoromethoxy)benzenesulfonyl chloride (CAS 1804936-65-9) is a high-purity analytical reference standard with the molecular formula C7H3Cl3F2O3S and a molecular weight of 311.52 g/mol.

The molecular framework of 2,3-Dichloro-5-(difluoromethoxy)benzenesulfonyl chloride (C7H3Cl3F2O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 2,3-Dichloro-5-(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.
