Chemical Structure

N-Cyclohexyl-6-(methylsulfanyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine CAS 478247-63-1 chemical structure

Description

The occurrence of N-Cyclohexyl-6-(methylsulfanyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-Cyclohexyl-6-(methylsulfanyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (CAS 478247-63-1) is a high-purity analytical reference standard with the molecular formula C18H21N5S and a molecular weight of 339.46 g/mol.

The molecular framework of N-Cyclohexyl-6-(methylsulfanyl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (C18H21N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
