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 7-Methyl-1-benzothiophene-3-carboxylic acid.
CATO supplies 7-Methyl-1-benzothiophene-3-carboxylic acid (CAS 1505-60-8), a certified reference material (molecular formula C10H8O2S, MW 192.23 g/mol) for analytical method development and quality control.
The molecular framework of 7-Methyl-1-benzothiophene-3-carboxylic acid (C10H8O2S) 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.
CATO manufactures 7-Methyl-1-benzothiophene-3-carboxylic acid 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.
