Used as a key intermediate in organic synthesis, particularly in the preparation of phosphonate-based compounds with biological activity. Its structure allows for the introduction of functionalized alkyl chains in the development of pharmaceuticals and agrochemicals. Commonly employed in Horner-Wadsworth-Emmons reactions to form carbon-carbon double bonds, enabling the synthesis of complex molecules such as potential enzyme inhibitors or bioactive analogs. Also finds use in research settings for modifying molecular frameworks in medicinal chemistry projects.
