2-(5-Methylthiophen-2-yl)propanoic acid CAS 50845-91-5

Description

2-(5-Methylthiophen-2-yl)propanoic acid (CAS 50845-91-5) is a high-purity analytical reference standard with the molecular formula C8H10O2S and a molecular weight of 170.23 g/mol.

The molecular framework of 2-(5-Methylthiophen-2-yl)propanoic acid (C8H10O2S) 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.

As a certified reference material (CRM), 2-(5-Methylthiophen-2-yl)propanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
