Used as a coupling agent in organic synthesis, particularly in the preparation of silane-based crosslinking agents for moisture-curable polymers. It enhances adhesion between organic polymers and inorganic substrates, making it valuable in sealants, coatings, and adhesives. Commonly employed in the production of specialty silicones where hydrolytic stability and improved performance are required. Its alkyne functionality allows for further chemical modifications via click chemistry or metal-catalyzed reactions, useful in pharmaceutical and material science applications.
