2-Chloro-4-methoxybenzene-1-sulfonyl chloride CAS 23094-94-2

Description

Compared with other compounds in its class, the molecular weight of 241.09 g/mol gives 2-Chloro-4-methoxybenzene-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Chloro-4-methoxybenzene-1-sulfonyl chloride (CAS 23094-94-2), a certified reference material (molecular formula C7H6Cl2O3S, MW 241.09 g/mol) for analytical method development and quality control.

The molecular framework of 2-Chloro-4-methoxybenzene-1-sulfonyl chloride (C7H6Cl2O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. 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.

CATO manufactures 2-Chloro-4-methoxybenzene-1-sulfonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
