Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring tertiary amine functionalities. Its quaternary ammonium derivatives serve in the production of disinfectants and surfactants due to enhanced solubility and stability. Also employed in agrochemical formulations to improve efficacy of crop protection agents. Acts as a building block in specialty polymers, contributing to improved thermal and chemical resistance in coatings and resins.
