Chemical Structure
Description
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.
CATO supplies 4-((3-Bromobenzylidene)amino)-3-(2-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478256-45-0), a certified reference material (molecular formula C16H13BrN4OS, MW 389.27 g/mol) for analytical method development and quality control.
4-((3-Bromobenzylidene)amino)-3-(2-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (C16H13BrN4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
