2-Bromo-4-(3,5-difluorophenyl)thiazole (CAS 886367-95-9) is a high-purity analytical reference standard with the molecular formula C9H4BrF2NS and a molecular weight of 276.10 g/mol.
2-Bromo-4-(3,5-difluorophenyl)thiazole (C9H4BrF2NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
