Application

4-Hydroxynaphthyldimethylsulfonium triflate is primarily used as a photoacid generator (PAG) in advanced photoresist formulations for semiconductor lithography, where it decomposes upon UV exposure to release strong acids for pattern development. It also serves as a key intermediate in organic synthesis, particularly for constructing sulfonium-based functional materials. Researchers leverage its reactivity in polymer crosslinking and cationic polymerization processes.
