1,1,1-Trifluoro-N-[(11bR)-8,9,10,11,12,13,14,15-octahydro-2,6-di-2-naphthalenyl-4-oxidodinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-yl]methanesulfonamide (CAS 1261302-61-7), molecular formula C41H33F3NO5PS and molecular weight 739.74 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,1-Trifluoro-N-[(11bR)-8,9,10,11,12,13,14,15-octahydro-2,6-di-2-naphthalenyl-4-oxidodinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-yl]methanesulfonamide (C41H33F3NO5PS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
