Chemical Structure

n-(4-Ethylcyclohexyl)-3-(pyrrolidin-1-yl)aniline CAS 1178166-75-0 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-(4-Ethylcyclohexyl)-3-(pyrrolidin-1-yl)aniline (CAS 1178166-75-0), a certified reference material (molecular formula C18H28N2, MW 272.43 g/mol) for analytical method development and quality control.

The molecular framework of n-(4-Ethylcyclohexyl)-3-(pyrrolidin-1-yl)aniline (C18H28N2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
