(4S)-2-[[3-[(4,5-Dihydro-2-oxazolyl)methyl]-5-[[(4S)-4,5-dihydro-4-phenyl-2-oxazolyl]methyl]-2,4,6-trimethylphenyl]methyl]-4,5-dihydro-4-phenyloxazole (CAS 774577-30-9), molecular formula C31H31N3O3 and molecular weight 493.60 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C31H31N3O3, (4S)-2-[[3-[(4,5-Dihydro-2-oxazolyl)methyl]-5-[[(4S)-4,5-dihydro-4-phenyl-2-oxazolyl]methyl]-2,4,6-trimethylphenyl]methyl]-4,5-dihydro-4-phenyloxazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 493.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
