Used as a key intermediate in the synthesis of organophosphorus compounds, particularly in pharmaceuticals and agrochemicals. Its structure allows for the introduction of phosphonate groups into larger molecules, enhancing stability and bioavailability. Commonly employed in the development of enzyme inhibitors due to its ability to mimic phosphate esters in metabolic pathways. Also utilized in research for modifying peptides and nucleotides, where the acetamidomethyl group acts as a protective moiety while the phosphonic acid provides water solubility and binding affinity.
