5,5’-Bis(diphenylphosphino)-4,4’-bi-1,3-benzodioxole CAS 244261-75-4

Description

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5,5’-Bis(diphenylphosphino)-4,4’-bi-1,3-benzodioxole is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 610.57 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).
