Used as a flame retardant in various materials, including textiles and plastics, due to its ability to inhibit combustion. It is also employed as a stabilizer in polymer production to enhance thermal and chemical resistance. In water treatment, it acts as a scale inhibitor, preventing the buildup of mineral deposits. Additionally, it serves as a chelating agent in industrial processes to bind and remove metal ions. Its applications extend to the synthesis of specialty chemicals and intermediates in organic chemistry.
