Chemical Structure
Description
3-Methoxy-3-oxo-2-(thiophen-2-ylmethyl)propanoic acid (CAS 122308-24-1), molecular formula C9H10O4S and molecular weight 214.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methoxy-3-oxo-2-(thiophen-2-ylmethyl)propanoic acid (C9H10O4S) 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 the polarity and ionization state of its functional groups, 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 3-Methoxy-3-oxo-2-(thiophen-2-ylmethyl)propanoic 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.
