Used as a flame retardant additive in polymers and resins due to its ability to promote char formation and reduce flammability. It is also employed in the synthesis of bioactive compounds and pharmaceuticals, where it serves as a building block for molecules with biological activity. Additionally, it functions as a complexing agent in metal ion coordination and can be used in surface treatments to improve adhesion and corrosion resistance in coatings. Its amino and phosphate groups make it suitable for modifying biomaterials and in some cases, as a component in electrolytes for electrochemical applications.
