(4S,4'S,5R,5'R)-2,2'-(1,3-Bis(4-(tert-butyl)phenyl)propane-2,2-diyl)bis(4,5-diphenyl-4,5-dihydrooxazole) (CAS 2361262-51-1), molecular formula C53H54N2O2 and molecular weight 751.01 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4S,4'S,5R,5'R)-2,2'-(1,3-Bis(4-(tert-butyl)phenyl)propane-2,2-diyl)bis(4,5-diphenyl-4,5-dihydrooxazole) (C53H54N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 751.01 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
