Used in organic synthesis as an intermediate for pharmaceuticals and functional materials. Its alkyne and ketone functional groups allow participation in click chemistry, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and bioconjugation. Also employed in the preparation of liquid crystals and photoactive compounds due to its rigid aromatic structure and reactive handles for further modification. Suitable for polymer chemistry to introduce cross-linking sites or modify material properties.
