Chemical Structure

(11bR)-4-Hydroxy-2,6-bis(triphenylsilyl)-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide CAS 957790-94-2 chemical structure

Description

The occurrence of (11bR)-4-Hydroxy-2,6-bis(triphenylsilyl)-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(11bR)-4-Hydroxy-2,6-bis(triphenylsilyl)-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide (CAS 957790-94-2) is a high-purity analytical reference standard with the molecular formula C56H49O4PSi2 and a molecular weight of 873.13 g/mol.

The molecular framework of (11bR)-4-Hydroxy-2,6-bis(triphenylsilyl)-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1’,2’-f][1,3,2]dioxaphosphepine 4-Oxide (C56H49O4PSi2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
