Chemical Structure

4-(5-Methyl-1h-pyrazol-1-yl)benzenamine CAS 374814-14-9 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 4-(5-Methyl-1h-pyrazol-1-yl)benzenamine (CAS 374814-14-9), a certified reference material (molecular formula C10H11N3, MW 173.21 g/mol) for analytical method development and quality control.

The molecular framework of 4-(5-Methyl-1h-pyrazol-1-yl)benzenamine (C10H11N3) 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).

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.
