Description

The occurrence of Methyl 3-methylbenzo[b]thiophene-2-carboxylate 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.

Methyl 3-methylbenzo[b]thiophene-2-carboxylate (CAS 3133-81-1), molecular formula C11H10O2S and molecular weight 206.26 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H10O2S, Methyl 3-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
