2-Methoxy-3,5-dimethylbenzene-1-sulfonyl chloride CAS 749268-53-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methoxy-3,5-dimethylbenzene-1-sulfonyl chloride.

CATO supplies 2-Methoxy-3,5-dimethylbenzene-1-sulfonyl chloride (CAS 749268-53-9), a certified reference material (molecular formula C9H11ClO3S, MW 234.70 g/mol) for analytical method development and quality control.

The molecular framework of 2-Methoxy-3,5-dimethylbenzene-1-sulfonyl chloride (C9H11ClO3S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-Methoxy-3,5-dimethylbenzene-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.
