Used primarily as a reactive intermediate in the synthesis of various specialty chemicals, including pharmaceuticals, agrochemicals, and functional polymers. Its high reactivity allows for ring-opening reactions that introduce amino functionalities into larger molecules, making it valuable in the production of surfactants, emulsifiers, and water-treatment additives. Also employed in crosslinking agents for resins and coatings, enhancing durability and chemical resistance. Due to its ability to form cationic polymers, it finds use in flocculants for wastewater treatment and in papermaking to improve dry strength. Handle with care, as it is highly reactive and potentially hazardous.
