Chemical Structure

3-(Methoxycarbonyl)benzo[b]thiophene-2-carboxylic acid CAS 87807-50-9 chemical structure

Description

The occurrence of 3-(Methoxycarbonyl)benzo[b]thiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(Methoxycarbonyl)benzo[b]thiophene-2-carboxylic acid (CAS 87807-50-9), a certified reference material (molecular formula C11H8O4S, MW 236.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H8O4S, 3-(Methoxycarbonyl)benzo[b]thiophene-2-carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
