Chemical Structure

Methyl 2-Thiophenecarboxylate CAS 5380-42-7 chemical structure

Description

Methyl 2-Thiophenecarboxylate (CAS 5380-42-7), molecular formula C6H6O2S and molecular weight 142.18 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 2-Thiophenecarboxylate (C6H6O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 Methyl 2-Thiophenecarboxylate 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.
