4-Isopropyl-N-p-tolylaniline CAS 494834-22-9

Description

The occurrence of 4-Isopropyl-N-p-tolylaniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Isopropyl-N-p-tolylaniline (CAS 494834-22-9), molecular formula C16H19N and molecular weight 225.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Isopropyl-N-p-tolylaniline (C16H19N) 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.

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.
