Used as a crosslinking agent in the synthesis of advanced polymer networks, particularly in thermosetting resins and shape-memory materials. Its dual alkyne functionality enables efficient click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in bioconjugation, surface modification, and the development of functional coatings. Also employed in the preparation of conjugated microporous polymers and as a building block in organic frameworks for catalysis and sensing applications.
