Chemical Structure
Description
3-amino-5,6-dimethyl-1H,4H,5H-pyrazolo[4,3-c]pyridin-4-one (CAS 68464-91-5), molecular formula C8H10N4O and molecular weight 178.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-amino-5,6-dimethyl-1H,4H,5H-pyrazolo[4,3-c]pyridin-4-one (C8H10N4O) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
CATO manufactures 3-amino-5,6-dimethyl-1H,4H,5H-pyrazolo[4,3-c]pyridin-4-one 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.
