Used as a reagent in organic synthesis, particularly in the preparation of phosphazenes and other phosphorus-containing compounds. It serves as a key intermediate in the development of flame retardants, which are essential in enhancing the fire resistance of materials like plastics and textiles. Additionally, it plays a role in the synthesis of ligands for catalysis, aiding in various chemical reactions, including polymerization and cross-coupling processes. Its application extends to the field of material science, where it contributes to the creation of advanced polymers with tailored properties.
