N-(4-(4-Chlorophenoxy)phenyl)-1-(3,4-dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine CAS 890887-23-7

Description

N-(4-(4-Chlorophenoxy)phenyl)-1-(3,4-dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (CAS 890887-23-7) is a high-purity analytical reference standard with the molecular formula C25H20ClN5O and a molecular weight of 441.91 g/mol.

The molecular framework of N-(4-(4-Chlorophenoxy)phenyl)-1-(3,4-dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (C25H20ClN5O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
