Tetraphenylcyclopentadienone（Cat No.:R070936）is an aromatic compound consisting of a cyclopentadienone core substituted with four phenyl groups at the 2, 3, 4, and 5 positions. This deep purple solid is widely used in organic synthesis and materials chemistry, particularly as a diene component in Diels–Alder reactions. Its extended conjugation and rigid structure make it a valuable building block for polycyclic aromatic hydrocarbons and organic electronic materials. The phenyl groups enhance solubility and stabilize the molecule through resonance. It also serves as a precursor in the synthesis of graphene-like structures and molecular semiconductors.
