Methyl 5-(chlorosulfonyl)-2-(trifluoromethoxy)benzoate CAS 2137562-31-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5-(chlorosulfonyl)-2-(trifluoromethoxy)benzoate.

CATO supplies Methyl 5-(chlorosulfonyl)-2-(trifluoromethoxy)benzoate (CAS 2137562-31-1), a certified reference material (molecular formula C9H6ClF3O5S, MW 318.65 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, Methyl 5-(chlorosulfonyl)-2-(trifluoromethoxy)benzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Methyl 5-(chlorosulfonyl)-2-(trifluoromethoxy)benzoate 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.
