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.
2-(3-Ethyl-1h-1,2,4-triazol-5-yl)aniline (CAS 1090921-40-6), molecular formula C10H12N4 and molecular weight 188.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Ethyl-1h-1,2,4-triazol-5-yl)aniline (C10H12N4) 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.
As a certified reference material (CRM), 2-(3-Ethyl-1h-1,2,4-triazol-5-yl)aniline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
