Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Phenyl-4-(4-phenylpiperazin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine (CAS 393845-64-2) is a high-purity analytical reference standard with the molecular formula C21H20N6 and a molecular weight of 356.42 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Phenyl-4-(4-phenylpiperazin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
