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.
4-((4-Bromobenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 573973-61-2) is a high-purity analytical reference standard with the molecular formula C15H10BrFN4S and a molecular weight of 377.23 g/mol.
The molecular framework of 4-((4-Bromobenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (C15H10BrFN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
