Application

Toliodium chloride is widely used as a photoacid generator (PAG) in photoresist formulations for semiconductor manufacturing. It facilitates efficient cationic polymerization in UV-curable coatings and adhesives. Researchers also employ it as an arylating agent in palladium-catalyzed cross-coupling reactions to construct complex organic frameworks. Its stability under acidic conditions makes it suitable for catalytic systems in synthetic chemistry.
