Used primarily as a flame retardant in various polymers and plastics, it enhances fire resistance by forming a protective char layer when exposed to flames. It is also employed in the synthesis of specialty chemicals, where it acts as a stabilizer or additive to improve material properties. Additionally, it finds application in lubricants and hydraulic fluids to reduce wear and enhance performance under high-temperature conditions. Its chelating properties make it useful in water treatment processes to control scale formation and inhibit corrosion in industrial systems.
