Used as a key intermediate in the synthesis of functional polymers and crosslinking agents, particularly in the development of thermosetting resins and specialty coatings. Its aldehyde and allyl functional groups enable participation in a variety of reactions, including condensation and radical curing processes. Commonly employed in the preparation of fluorescent organic materials and sensors due to its ability to form conjugated systems. Also finds use in the design of porous organic frameworks and gels, where its rigid aromatic core and reactive side chains support network formation. Valued in research for constructing stimuli-responsive materials and functional hydrogels with potential applications in drug delivery and environmental remediation.
