Chemical Structure
Description
The molecular framework of 5-(4-ethylphenyl)-1,2,4-triazin-3-amine (C11H12N4) 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).
5-(4-ethylphenyl)-1,2,4-triazin-3-amine (CAS 1094385-32-6) is a high-purity analytical reference standard with the molecular formula C11H12N4 and a molecular weight of 200.24 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
