Description

(11bR)-8,9,10,11,12,13,14,15-Octahydro-4-hydroxy-2,6-bis(2,4,6-tricyclohexylphenyl)-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin 4-oxide (CAS 1676072-26-6) is a high-purity analytical reference standard with the molecular formula C68H89O4P and a molecular weight of 1001.41 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (11bR)-8,9,10,11,12,13,14,15-Octahydro-4-hydroxy-2,6-bis(2,4,6-tricyclohexylphenyl)-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin 4-oxide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1001.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
