Description
CATO supplies Methyl 5-(thiophen-2-yl)thiophene-2-carboxylate (CAS 3515-21-7), a certified reference material (molecular formula C10H8O2S2, MW 224.30 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 5-(thiophen-2-yl)thiophene-2-carboxylate (C10H8O2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Methyl 5-(thiophen-2-yl)thiophene-2-carboxylate 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.
