(11bR)-8,9,10,11,12,13,14,15-Octahydro-4-hydroxy-2,6-bis([1,1':3',1''-terphenyl]-5'-yl)-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin CAS 1569807-15-3 chemical structure

Description

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.

(11bR)-8,9,10,11,12,13,14,15-Octahydro-4-hydroxy-2,6-bis([1,1':3',1''-terphenyl]-5'-yl)-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin (CAS 1569807-15-3) is a high-purity analytical reference standard with the molecular formula C56H45O4P and a molecular weight of 812.93 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([1,1':3',1''-terphenyl]-5'-yl)-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 812.93 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
