Chemical Structure
Description
The occurrence of (11bS)-N-((S)-1-(2-(diphenylphosphanyl)phenyl)ethyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(11bS)-N-((S)-1-(2-(diphenylphosphanyl)phenyl)ethyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (CAS 913265-32-4), molecular formula C40H31NO2P2 and molecular weight 619.63 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C40H31NO2P2, (11bS)-N-((S)-1-(2-(diphenylphosphanyl)phenyl)ethyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 619.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
