Used as a building block in organic synthesis, particularly in the production of liquid crystals and pharmaceuticals. It serves as an intermediate in the preparation of conjugated materials for optoelectronic devices, such as OLEDs and organic semiconductors. Its alkyne functionality allows for use in click chemistry and palladium-catalyzed coupling reactions, enabling the construction of complex aromatic structures. Also employed in the synthesis of specialty polymers and agrochemicals due to its reactive aromatic and alkyne groups.
