Chemical Structure

(11bS)-2,6-bis[3,5-bis(trifluoromethyl)phenyl]-N,N-bis[(1R)-1-phenylethyl]-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine CAS 1642864-21-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 963.79 g/mol gives (11bS)-2,6-bis[3,5-bis(trifluoromethyl)phenyl]-N,N-bis[(1R)-1-phenylethyl]-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(11bS)-2,6-bis[3,5-bis(trifluoromethyl)phenyl]-N,N-bis[(1R)-1-phenylethyl]-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (CAS 1642864-21-8) is a high-purity analytical reference standard with the molecular formula C52H34F12NO2P and a molecular weight of 963.79 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, (11bS)-2,6-bis[3,5-bis(trifluoromethyl)phenyl]-N,N-bis[(1R)-1-phenylethyl]-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 963.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
