Chemical Structure
Description
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.
CATO supplies 4-Amino-1-tert-butyl-3-(1-naphthyl)pyrazolo[3,4-d]pyrimidine (CAS 221243-82-9), a certified reference material (molecular formula C19H19N5, MW 317.39 g/mol) for analytical method development and quality control.
The molecular framework of 4-Amino-1-tert-butyl-3-(1-naphthyl)pyrazolo[3,4-d]pyrimidine (C19H19N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
