4-(2-Bromo-4-methylphenyl)-3-(thiophen-2-yl)-1H-1,2,4-triazole-5(4H)-thione (CAS 728013-67-0) is a high-purity analytical reference standard with the molecular formula C13H10BrN3S2 and a molecular weight of 352.27 g/mol.
4-(2-Bromo-4-methylphenyl)-3-(thiophen-2-yl)-1H-1,2,4-triazole-5(4H)-thione (C13H10BrN3S2) 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 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
