Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

5-amino-1-benzyl-1H,4H,5H-pyrazolo[3,4-d]pyrimidin-4-one (CAS 905244-78-2) is a high-purity analytical reference standard with the molecular formula C12H23N5O and a molecular weight of 253.34 g/mol.

Structurally, 5-amino-1-benzyl-1H,4H,5H-pyrazolo[3,4-d]pyrimidin-4-one (C12H23N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 253.34 g/mol, it falls into the medium-molecular-weight range. 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.
