N-((4-Oxo-1-phenyl-4,7-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-yl)methyl)acetamide CAS 951987-97-6

Description

Compared with other compounds in its class, the molecular weight of 283.29 g/mol gives N-((4-Oxo-1-phenyl-4,7-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-yl)methyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-((4-Oxo-1-phenyl-4,7-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-yl)methyl)acetamide (CAS 951987-97-6), molecular formula C14H13N5O2 and molecular weight 283.29 g/mol, is a CATO reference standard with documented purity and traceability.

N-((4-Oxo-1-phenyl-4,7-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-yl)methyl)acetamide (C14H13N5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
