Used as a crosslinking agent in polymer chemistry, particularly in the development of specialty resins and coatings. Its reactive alkyne groups enable efficient click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), allowing for the construction of complex polymer networks with high precision. Commonly applied in the synthesis of functional materials for electronics, adhesives, and 3D printing due to its ability to form stable, rigid structures upon curing. Also employed in research settings for bioconjugation and surface modification where controlled, modular reactivity is required.
