Description
CATO manufactures 3-Methylthieno[3,2-c]pyridine-4-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 3-Methylthieno[3,2-c]pyridine-4-carboxylic acid (CAS 1780187-03-2), a certified reference material (molecular formula C9H7NO2S, MW 193.22 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methylthieno[3,2-c]pyridine-4-carboxylic acid (C9H7NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
