Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid.
CATO supplies 6-Methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid (CAS 900137-02-2), a certified reference material (molecular formula C10H12O2S, MW 196.27 g/mol) for analytical method development and quality control.
The molecular framework of 6-Methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid (C10H12O2S) 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.
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.
