3-{[(4-bromophenyl)methyl]sulfanyl}-5-({[(2,6-dichlorophenyl)methyl]sulfanyl}methyl)-4-ethyl-4H-1,2,4-triazole 344270-90-2 7H-465S (CAS 344270-90-2), molecular formula C19H18BrCl2N3S2 and molecular weight 503.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-{[(4-bromophenyl)methyl]sulfanyl}-5-({[(2,6-dichlorophenyl)methyl]sulfanyl}methyl)-4-ethyl-4H-1,2,4-triazole 344270-90-2 7H-465S (C19H18BrCl2N3S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 503.31 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
