Methyl 6-methylbenzo[b]thiophene-2-carboxylate CAS 82787-72-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 6-methylbenzo[b]thiophene-2-carboxylate.

Methyl 6-methylbenzo[b]thiophene-2-carboxylate (CAS 82787-72-2) is a high-purity analytical reference standard with the molecular formula C11H10O2S and a molecular weight of 206.26 g/mol.

Based on its molecular formula C11H10O2S, Methyl 6-methylbenzo[b]thiophene-2-carboxylate 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 206.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
