Used as a curing agent for epoxy resins, providing strong mechanical properties and chemical resistance in coatings, adhesives, and composites. Commonly applied in the aerospace, automotive, and electrical industries for encapsulation and insulation due to its excellent thermal stability. Also serves as a chelating agent in water treatment and agriculture to control metal ions. In medicine, it is used in chelation therapy for copper overload conditions such as Wilson’s disease. Additionally, employed in the synthesis of dyes, surfactants, and corrosion inhibitors.
