Chemical Structure
Description
Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, (2R,4R)-Pentane-2,4-diylbis(bis(4-fluorophenyl)phosphine) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 512.46 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).
