CATO supplies (R)-4-benzyl-2-(6-phenylpyridin-2-yl)-4,5-dihydrooxazole (CAS 2757082-55-4), a certified reference material (molecular formula C21H18N2O, MW 314.38 g/mol) for analytical method development and quality control.
(R)-4-benzyl-2-(6-phenylpyridin-2-yl)-4,5-dihydrooxazole (C21H18N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
