Ethyl 4-(2-hydroxyethyl)-3-methylbenzo[b]thiophene-6-carboxylate CAS 2691128-76-2

Description

The occurrence of Ethyl 4-(2-hydroxyethyl)-3-methylbenzo[b]thiophene-6-carboxylate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 4-(2-hydroxyethyl)-3-methylbenzo[b]thiophene-6-carboxylate (CAS 2691128-76-2), molecular formula C14H16O3S and molecular weight 264.34 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 4-(2-hydroxyethyl)-3-methylbenzo[b]thiophene-6-carboxylate (C14H16O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
