1-(3-Chloro-4-methylphenyl)-N-(4-(4-chlorophenoxy)phenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (CAS 890893-80-8) is a high-purity analytical reference standard with the molecular formula C24H17Cl2N5O and a molecular weight of 462.33 g/mol.
Structurally, 1-(3-Chloro-4-methylphenyl)-N-(4-(4-chlorophenoxy)phenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (C24H17Cl2N5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 462.33 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
