Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3,4-Diphenyl-1h-pyrrole-2,5-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.26 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).
3,4-Diphenyl-1h-pyrrole-2,5-dione (CAS 31295-36-0) is a high-purity analytical reference standard with the molecular formula C16H11NO2 and a molecular weight of 249.26 g/mol.
