Chemical Structure

Methyl 2-(chlorosulfonyl)-5-ethylbenzoate CAS 1247825-38-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 262.71 g/mol gives Methyl 2-(chlorosulfonyl)-5-ethylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 2-(chlorosulfonyl)-5-ethylbenzoate (CAS 1247825-38-2), a certified reference material (molecular formula C10H11ClO4S, MW 262.71 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Methyl 2-(chlorosulfonyl)-5-ethylbenzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 2-(chlorosulfonyl)-5-ethylbenzoate 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.
