Chemical Structure
Description
Ethyl 3-amino-6-oxo-1h,6h,7h-pyrazolo[3,4-b]pyridine-5-carboxylate (CAS 851879-18-0), molecular formula C9H10N4O3 and molecular weight 222.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 3-amino-6-oxo-1h,6h,7h-pyrazolo[3,4-b]pyridine-5-carboxylate (C9H10N4O3) 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.
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 Ethyl 3-amino-6-oxo-1h,6h,7h-pyrazolo[3,4-b]pyridine-5-carboxylate 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.
