Description

Compared with other compounds in its class, the molecular weight of 206.24 g/mol gives 4-methanesulfonylthiophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-methanesulfonylthiophene-2-carboxylic acid (CAS 100704-38-9), a certified reference material (molecular formula C6H6O4S2, MW 206.24 g/mol) for analytical method development and quality control.

4-methanesulfonylthiophene-2-carboxylic acid (C6H6O4S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 4-methanesulfonylthiophene-2-carboxylic acid 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.
