Description
CATO manufactures 2,3,4,5-Tetrahydrobenzo[b]thiepine-7-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.
CATO supplies 2,3,4,5-Tetrahydrobenzo[b]thiepine-7-carboxylic acid (CAS 226259-91-2), a certified reference material (molecular formula C11H12O2S, MW 208.28 g/mol) for analytical method development and quality control.
The molecular framework of 2,3,4,5-Tetrahydrobenzo[b]thiepine-7-carboxylic acid (C11H12O2S) 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.
