(11bR)​-2,​6-​Bis([1,​1'-​biphenyl]​-​4-​yl)​-​8,​9,​10,​11,​12,​13,​14,​15-​octahydro-​4-​hydroxy-4-​oxide-dinaphtho[2,​1-​d:1',​2'-​f]​[1,​3,​2]​dioxaphosphepin CAS 861909-35-5 chemical structure

Description

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (11bR)​-2,​6-​Bis([1,​1'-​biphenyl]​-​4-​yl)​-​8,​9,​10,​11,​12,​13,​14,​15-​octahydro-​4-​hydroxy-4-​oxide-dinaphtho[2,​1-​d:1',​2'-​f]​[1,​3,​2]​dioxaphosphepin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 660.74 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.

(11bR)​-2,​6-​Bis([1,​1'-​biphenyl]​-​4-​yl)​-​8,​9,​10,​11,​12,​13,​14,​15-​octahydro-​4-​hydroxy-4-​oxide-dinaphtho[2,​1-​d:1',​2'-​f]​[1,​3,​2]​dioxaphosphepin (CAS 861909-35-5) is a high-purity analytical reference standard with the molecular formula C44H37O4P and a molecular weight of 660.74 g/mol.

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.
