Used primarily as a crosslinking agent in polymer chemistry, enabling the formation of highly rigid and thermally stable networks. Its activated alkyne groups readily participate in click chemistry reactions, especially in thiol-yne and azide-yne couplings, making it valuable in material science for creating functional coatings, photoresists, and 3D-printed structures. Also employed in the synthesis of specialty monomers for high-performance resins and in biomedical applications where controlled, rapid curing is required. Its reactivity allows for efficient UV-initiated curing without the need for photoinitiators in some systems.
