Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4-Bromobenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione.
4-((4-Bromobenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478256-00-7) is a high-purity analytical reference standard with the molecular formula C16H13BrN4S and a molecular weight of 373.27 g/mol.
4-((4-Bromobenzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (C16H13BrN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
