3-{[(2,6-dichlorophenyl)methyl]sulfanyl}-4-ethyl-5-[2-(methylsulfanyl)phenyl]-4H-1,2,4-triazole (CAS 339015-37-1), molecular formula C18H17Cl2N3S2 and molecular weight 410.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-{[(2,6-dichlorophenyl)methyl]sulfanyl}-4-ethyl-5-[2-(methylsulfanyl)phenyl]-4H-1,2,4-triazole (C18H17Cl2N3S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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 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).
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.
