Used as a key reagent in organic synthesis, particularly in the preparation of phosphorylated compounds with biological activity. Its structure allows it to participate in Horner-Wadsworth-Emmons reactions, enabling the formation of conjugated systems such as α,β-unsaturated nitriles, which are valuable intermediates in pharmaceuticals and agrochemicals. The presence of both cyano and phosphonate groups provides dual functionality for further chemical transformations, making it useful in the development of novel drug candidates and functional materials.
