Methyl 4-acetyl-3-methyl-5-(methylthio)thiophene-2-carboxylate (CAS 175201-84-0) is a high-purity analytical reference standard with the molecular formula C10H12O3S2 and a molecular weight of 244.33 g/mol.
The molecular framework of Methyl 4-acetyl-3-methyl-5-(methylthio)thiophene-2-carboxylate (C10H12O3S2) 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).
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 4-acetyl-3-methyl-5-(methylthio)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.
