Description

Compared with other compounds in its class, the molecular weight of 222.26 g/mol gives Ethyl 7-hydroxybenzo[b]thiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 7-hydroxybenzo[b]thiophene-2-carboxylate (CAS 1956371-74-6), molecular formula C11H10O3S and molecular weight 222.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 7-hydroxybenzo[b]thiophene-2-carboxylate (C11H10O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures Ethyl 7-hydroxybenzo[b]thiophene-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
