Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, fluorine substitution, 3-(Ethylsulfanyl)-5-(trifluoromethyl)-4h-1,2,4-triazol-4-amine is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 3-(Ethylsulfanyl)-5-(trifluoromethyl)-4h-1,2,4-triazol-4-amine (CAS 459210-90-3), a certified reference material (molecular formula C5H7F3N4S, MW 212.20 g/mol) for analytical method development and quality control.
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.
