Chemical Structure
Description
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.
(5-Chloro-2-methoxyphenyl)methanesulfonyl chloride (CAS 1179047-05-2), molecular formula C8H8Cl2O3S and molecular weight 255.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5-Chloro-2-methoxyphenyl)methanesulfonyl chloride (C8H8Cl2O3S) 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. 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).
CATO manufactures (5-Chloro-2-methoxyphenyl)methanesulfonyl 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.
