4-((5-Bromo-2-hydroxybenzylidene)amino)-3-(pyridin-2-yl)-1H-1,2,4-triazole-5(4H)-thione CAS 497823-59-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 4-((5-Bromo-2-hydroxybenzylidene)amino)-3-(pyridin-2-yl)-1H-1,2,4-triazole-5(4H)-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

4-((5-Bromo-2-hydroxybenzylidene)amino)-3-(pyridin-2-yl)-1H-1,2,4-triazole-5(4H)-thione (CAS 497823-59-3), molecular formula C14H10BrN5OS and molecular weight 376.23 g/mol, is a CATO reference standard with documented purity and traceability.

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.
