(11bR,11'bR)-4,4'-[(1S,2S)-1,2-Diphenyl-1,2-ethanediyl]bis[4,5-dihydro-3H-dinaphth[2,1-c:1',2'-e]azepine (CAS 1256952-84-7), molecular formula C58H44N2 and molecular weight 768.98 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C58H44N2, (11bR,11'bR)-4,4'-[(1S,2S)-1,2-Diphenyl-1,2-ethanediyl]bis[4,5-dihydro-3H-dinaphth[2,1-c:1',2'-e]azepine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 768.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
