Chemical Structure

N-Ethyl-3-(4-pyridyl)aniline CAS 66375-90-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Ethyl-3-(4-pyridyl)aniline.

N-Ethyl-3-(4-pyridyl)aniline (CAS 66375-90-4) is a high-purity analytical reference standard with the molecular formula C13H14N2 and a molecular weight of 198.26 g/mol.

The molecular framework of N-Ethyl-3-(4-pyridyl)aniline (C13H14N2) 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.

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 manufactures N-Ethyl-3-(4-pyridyl)aniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
