N-(5-Chloro-2-methoxyphenyl)-1-(3,4-dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine CAS 890885-18-4

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-(5-Chloro-2-methoxyphenyl)-1-(3,4-dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

N-(5-Chloro-2-methoxyphenyl)-1-(3,4-dimethylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (CAS 890885-18-4) is a high-purity analytical reference standard with the molecular formula C20H18ClN5O and a molecular weight of 379.84 g/mol.

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.
