Used as a synthetic material intermediate. Serves as a precursor for fluorinated phosphazene polymers, elastomers, flame-retardant materials, and fluorinated functional materials. Investigated as a flame-retardant electrolyte additive for lithium-ion batteries. Also employed as a starting material/intermediate for preparing substituted phosphazenes and other phosphorus-nitrogen compounds.
