Description
CATO supplies 5-[({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)methyl]-4H,5H,6H,7H-pyrazolo[1,5-a]pyridine-3-carboxylic acid (CAS 2091446-70-5), a certified reference material (molecular formula C24H23N3O4, MW 417.46 g/mol) for analytical method development and quality control.
5-[({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)methyl]-4H,5H,6H,7H-pyrazolo[1,5-a]pyridine-3-carboxylic acid (C24H23N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 5-[({[(9H-fluoren-9-yl)methoxy]carbonyl}amino)methyl]-4H,5H,6H,7H-pyrazolo[1,5-a]pyridine-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.
