2-([1,1'-Biphenyl]-4-yl)-5-(trifluoromethyl)-1,3,4-oxadiazole (CAS 887267-97-2), molecular formula C15H9F3N2O and molecular weight 290.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-([1,1'-Biphenyl]-4-yl)-5-(trifluoromethyl)-1,3,4-oxadiazole (C15H9F3N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 290.24 g/mol, it falls into the medium-molecular-weight range. 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.
