Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-2-(2-Bromo-5-fluorophenyl)-4-(tert-butyl)-4,5-dihydrooxazole (CAS 1620784-45-3) is a high-purity analytical reference standard with the molecular formula C13H15BrFNO and a molecular weight of 300.17 g/mol.
(S)-2-(2-Bromo-5-fluorophenyl)-4-(tert-butyl)-4,5-dihydrooxazole (C13H15BrFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
