Chemical Structure

1-(2-Thienyl)cyclopentanecarboxylic acid CAS 202737-46-0 chemical structure

Description

Structurally, 1-(2-Thienyl)cyclopentanecarboxylic acid (C10H12O2S) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 196.27 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1-(2-Thienyl)cyclopentanecarboxylic acid (CAS 202737-46-0) is a high-purity analytical reference standard with the molecular formula C10H12O2S and a molecular weight of 196.27 g/mol.

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.
