Chemical Structure

6-Chloro-N-(4-methoxyphenyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine CAS 1040662-93-8 chemical structure

Description

The occurrence of 6-Chloro-N-(4-methoxyphenyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6-Chloro-N-(4-methoxyphenyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (CAS 1040662-93-8), a certified reference material (molecular formula C18H14ClN5O, MW 351.79 g/mol) for analytical method development and quality control.

The molecular framework of 6-Chloro-N-(4-methoxyphenyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (C18H14ClN5O) 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.
