(11bS,11'bS)-2,2'-[Oxybis(methylene)]bis[4-hydroxy-4,4'-dioxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin (CAS 1447217-75-5) is a high-purity analytical reference standard with the molecular formula C42H28O9P2 and a molecular weight of 738.61 g/mol.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (11bS,11'bS)-2,2'-[Oxybis(methylene)]bis[4-hydroxy-4,4'-dioxide-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 738.61 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).
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.
