1-(4-Bromophenyl)-1H-pyrrole-2,5-dione is an inhibitor of styrene polymerization. This compound was shown to inhibit styrene polymerization in a concentration dependent manner and has been used as a model for the evaluation of other inhibitors. The inhibition mechanism of 1-(4-bromophenyl)-1H-pyrrole-2,5-dione can be attributed to its ability to bind to the active site of the enzyme Styrene Synthase and block reaction by steric hindrance. It also inhibits fatty acid synthesis by blocking lipases. This compound has been used in copolymerization techniques with styrene and other monomers due to its stability in organic solvents. 1-(4-Bromophenyl)-1H-pyrrole-2,5-dione has also been shown to have a strong radiation sensitive effect on polystyrene films when used as a sensitizer in
