Chemical Structure

4-Hydroxy-1-phenylpyrazolo[3,4-d]pyrimidine CAS 21314-17-0 chemical structure

Description

The occurrence of 4-Hydroxy-1-phenylpyrazolo[3,4-d]pyrimidine 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.

4-Hydroxy-1-phenylpyrazolo[3,4-d]pyrimidine (CAS 21314-17-0), molecular formula C11H8N4O and molecular weight 212.21 g/mol, is a CATO reference standard with documented purity and traceability.

4-Hydroxy-1-phenylpyrazolo[3,4-d]pyrimidine (C11H8N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
