Compared with other compounds in its class, the molecular weight of 206.26 g/mol gives 3-(Benzo[b]thiophen-2-yl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(Benzo[b]thiophen-2-yl)propanoic acid (CAS 42768-60-5) is a high-purity analytical reference standard with the molecular formula C11H10O2S and a molecular weight of 206.26 g/mol.

Structurally, 3-(Benzo[b]thiophen-2-yl)propanoic acid (C11H10O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 206.26 g/mol, it falls into the medium-molecular-weight range. 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.

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.
