Used primarily as a catalyst in organic synthesis, particularly in the production of polyurethane foams and epoxy resins. It is also employed in the manufacture of ion-exchange resins, where it acts as a phase-transfer catalyst to enhance reaction rates. In analytical chemistry, it serves as a reagent for the determination of acidic compounds. Additionally, it finds application in the electronics industry for the development of semiconductors and as a component in photoresist developers. Its ability to act as a strong base makes it useful in various chemical reactions requiring deprotonation or neutralization.
