5-Chloro-2-(methanesulfonylmethyl)benzene-1-sulfonyl chloride CAS 1432678-37-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-2-(methanesulfonylmethyl)benzene-1-sulfonyl chloride.

CATO supplies 5-Chloro-2-(methanesulfonylmethyl)benzene-1-sulfonyl chloride (CAS 1432678-37-9), a certified reference material (molecular formula C8H8Cl2O4S2, MW 303.18 g/mol) for analytical method development and quality control.

Structurally, 5-Chloro-2-(methanesulfonylmethyl)benzene-1-sulfonyl chloride (C8H8Cl2O4S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 303.18 g/mol, it falls into the moderately-high-molecular-weight range. 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.

CATO manufactures 5-Chloro-2-(methanesulfonylmethyl)benzene-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.
