Chemical Structure
Description
The occurrence of 3-Methoxy-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid 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.
CATO supplies 3-Methoxy-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid (CAS 120715-48-2), a certified reference material (molecular formula C10H12O3S, MW 212.27 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methoxy-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid (C10H12O3S) 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 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.
