Compared with other compounds in its class, the molecular weight of 409.32 g/mol gives 4-(((5-Bromothiophen-2-yl)methylene)amino)-3-(3-ethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(((5-Bromothiophen-2-yl)methylene)amino)-3-(3-ethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 613249-88-0), molecular formula C15H13BrN4OS2 and molecular weight 409.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 4-(((5-Bromothiophen-2-yl)methylene)amino)-3-(3-ethoxyphenyl)-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 409.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
