Description
CATO supplies 3-(4-(4-Bromophenyl)-5-((2,6-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 477329-50-3), a certified reference material (molecular formula C20H13BrCl2N4S, MW 492.22 g/mol) for analytical method development and quality control.
Structurally, 3-(4-(4-Bromophenyl)-5-((2,6-dichlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (C20H13BrCl2N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 492.22 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).
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.
