[S(S)]-N-[(R)-[5-(Diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl]phenylmethyl]-2-methyl-2-propanesulfinamide (CAS 2162939-88-8), molecular formula C38H38NO2PS and molecular weight 603.75 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, [S(S)]-N-[(R)-[5-(Diphenylphosphino)-9,9-dimethyl-9H-xanthen-4-yl]phenylmethyl]-2-methyl-2-propanesulfinamide (C38H38NO2PS) 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 20.5, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 603.75 g/mol, it falls into the high-molecular-weight range. 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.
