Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-bromo-3-methyl-5-(trifluoromethyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-one (CAS 2648792-72-5) is a high-purity analytical reference standard with the molecular formula C7H10BrF3N4O and a molecular weight of 303.08 g/mol.
6-bromo-3-methyl-5-(trifluoromethyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-one (C7H10BrF3N4O) contains an amide group, a hydroxyl group, an ether linkage, 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.
