1-(4'-Aminophenyl)-1,2,4-triazole 1-(4-aminophenyl)-1,2,4-triazole 4-(1h-1,2,4-triazol-1-yl)aniline 4-[1,2,4]triazol-1-yl-phenylamine 6523-49-5 benzenamine, 4-(1h-1,2,4-triazol-1-yl)- triazolylaniline CAS 6523-49-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4'-Aminophenyl)-1,2,4-triazole 1-(4-aminophenyl)-1,2,4-triazole 4-(1h-1,2,4-triazol-1-yl)aniline 4-[1,2,4]triazol-1-yl-phenylamine 6523-49-5 benzenamine, 4-(1h-1,2,4-triazol-1-yl)- triazolylaniline.

CATO supplies 1-(4'-Aminophenyl)-1,2,4-triazole 1-(4-aminophenyl)-1,2,4-triazole 4-(1h-1,2,4-triazol-1-yl)aniline 4-[1,2,4]triazol-1-yl-phenylamine 6523-49-5 benzenamine, 4-(1h-1,2,4-triazol-1-yl)- triazolylaniline (CAS 6523-49-5), a certified reference material (molecular formula C8H18N4, MW 170.26 g/mol) for analytical method development and quality control.

The molecular framework of 1-(4'-Aminophenyl)-1,2,4-triazole 1-(4-aminophenyl)-1,2,4-triazole 4-(1h-1,2,4-triazol-1-yl)aniline 4-[1,2,4]triazol-1-yl-phenylamine 6523-49-5 benzenamine, 4-(1h-1,2,4-triazol-1-yl)- triazolylaniline (C8H18N4) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
