Used as an intermediate in organic synthesis, particularly in the preparation of organophosphorus compounds with potential applications in agrochemicals and pharmaceuticals. It serves as a reagent in the development of novel ligands and catalysts due to its ability to participate in phosphorylation and alkylation reactions. Also employed in research settings for the synthesis of bioactive molecules and functional materials. Its phosphonate group allows for chelation with metal ions, making it useful in coordination chemistry and the design of metal-organic frameworks.
