[S(R)]-N-[(S)-[3-(Benzyloxy)-2-(dicyclohexylphosphino)phenyl]-(2-naphthalenyl)methyl]-2-methyl-2-propanesulfinamide (CAS 2565792-69-8), molecular formula C40H50NO2PS and molecular weight 639.87 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, [S(R)]-N-[(S)-[3-(Benzyloxy)-2-(dicyclohexylphosphino)phenyl]-(2-naphthalenyl)methyl]-2-methyl-2-propanesulfinamide (C40H50NO2PS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.5, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 639.87 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
