Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(1-Piperazinyl)-1H-pyrazolo[3,4-d]pyrimidine dihydrochloride (CAS 853680-94-1), molecular formula C9H12N6HCl and molecular weight 240.69 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H12N6HCl, 4-(1-Piperazinyl)-1H-pyrazolo[3,4-d]pyrimidine dihydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
