The molecular framework of 3-(Methylthio)-5-(trifluoromethyl)-4h-1,2,4-triazol-4-amine (C4H5F3N4S) is characterized by a nitrile group, sulfur-containing functionality, fluorine substitution. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
3-(Methylthio)-5-(trifluoromethyl)-4h-1,2,4-triazol-4-amine (CAS 164352-65-2) is a high-purity analytical reference standard with the molecular formula C4H5F3N4S and a molecular weight of 198.17 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.
