1-(2-Aminophenyl)-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one CAS 1087784-31-3

Description

The occurrence of 1-(2-Aminophenyl)-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(2-Aminophenyl)-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one (CAS 1087784-31-3), a certified reference material (molecular formula C11H9N5O, MW 227.22 g/mol) for analytical method development and quality control.

Structurally, 1-(2-Aminophenyl)-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one (C11H9N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 227.22 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
