Chemical Structure

2-(thiophen-2-yl)propanoic acid CAS 54955-39-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 160.23 g/mol gives 2-(thiophen-2-yl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(thiophen-2-yl)propanoic acid (CAS 54955-39-4) is a high-purity analytical reference standard with the molecular formula C7H12O2S and a molecular weight of 160.23 g/mol.

The molecular framework of 2-(thiophen-2-yl)propanoic acid (C7H12O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
