Chemical Structure

N-Cyclopentyl-2-methyl-5-phenylpyrimidin-4-amine CAS 917896-08-3 chemical structure

Description

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.

CATO supplies N-Cyclopentyl-2-methyl-5-phenylpyrimidin-4-amine (CAS 917896-08-3), a certified reference material (molecular formula C16H19N3, MW 253.34 g/mol) for analytical method development and quality control.

The molecular framework of N-Cyclopentyl-2-methyl-5-phenylpyrimidin-4-amine (C16H19N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
