3-({[(4-chlorophenyl)methyl]sulfanyl}methyl)-4-ethyl-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazole (CAS 344268-92-4), molecular formula C20H19ClF3N3S2 and molecular weight 457.96 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 3-({[(4-chlorophenyl)methyl]sulfanyl}methyl)-4-ethyl-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 457.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
