Chemical Structure
Description
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.
22913-24-2 Benzo[b]thiophene-2-carboxylic acid methyl ester Methyl benzo[b]thiophene-2-carboxylate Methyl thianaphthene-2-carboxylate (CAS 22913-24-2) is a high-purity analytical reference standard with the molecular formula C10H16O2S and a molecular weight of 200.30 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 22913-24-2 Benzo[b]thiophene-2-carboxylic acid methyl ester Methyl benzo[b]thiophene-2-carboxylate Methyl thianaphthene-2-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 22913-24-2 Benzo[b]thiophene-2-carboxylic acid methyl ester Methyl benzo[b]thiophene-2-carboxylate Methyl thianaphthene-2-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
