Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 7-chlorothieno[3,2-b]pyridine-6-carboxylic acid (CAS 90690-94-1), a certified reference material (molecular formula C8H12ClNO2S, MW 221.70 g/mol) for analytical method development and quality control.
The molecular framework of 7-chlorothieno[3,2-b]pyridine-6-carboxylic acid (C8H12ClNO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 7-chlorothieno[3,2-b]pyridine-6-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.
