Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4H,5H,6H,7H-pyrazolo[1,5-a]pyridin-2-ylmethanamine dihydrochloride (CAS 1909336-24-8), molecular formula C8H13N3HCl and molecular weight 187.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4H,5H,6H,7H-pyrazolo[1,5-a]pyridin-2-ylmethanamine dihydrochloride (C8H13N3HCl) is characterized by a nitrile group, chlorine substitution. 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
