1,2,3,4,5-Pentamethylcyclopentadiene serves as a precursor to the ligand 1,2,3,4,5-pentamethylcyclopentadienyl. It is used as a growth modifier chemical, during metal organic chemical vapor deposition of iron from iron pentacarbonyl. It is used as a ligand in one-pot iridium-catalyzed transformation of alcohols to amides. Further, it acts as an electron mediator in the regeneration process of nicotinamide adenine dinucleotide. In addition to this, it undergoes radical cation catalyzed cycloaddition reaction with allenes to get Diels-Alder product.
