2-{1-methyl-4-oxo-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-5-yl}acetonitrile CAS 1341558-50-6

Description

Compared with other compounds in its class, the molecular weight of 189.17 g/mol gives 2-{1-methyl-4-oxo-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-5-yl}acetonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-{1-methyl-4-oxo-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-5-yl}acetonitrile (CAS 1341558-50-6), molecular formula C8H7N5O and molecular weight 189.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-{1-methyl-4-oxo-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-5-yl}acetonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 189.17 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).

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

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.
