Chemical Structure

4-Isopropylaminodiphenylamine CAS 101-72-4 chemical structure

Description

CATO supplies 4-Isopropylaminodiphenylamine (CAS 101-72-4), a certified reference material (molecular formula C15H18N2, MW 226.32 g/mol) for analytical method development and quality control.

The molecular framework of 4-Isopropylaminodiphenylamine (C15H18N2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 4-Isopropylaminodiphenylamine 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.
