Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Methyl-3H-imidazo[4,5-c]pyridine-7-carboxylic acid (CAS 1782640-32-7) is a high-purity analytical reference standard with the molecular formula C8H7N3O2 and a molecular weight of 177.16 g/mol.
The molecular framework of 3-Methyl-3H-imidazo[4,5-c]pyridine-7-carboxylic acid (C8H7N3O2) is characterized by an amino-acid-derived structure, an amide 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. 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 3-Methyl-3H-imidazo[4,5-c]pyridine-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.
