Used as a key intermediate in the synthesis of bioactive molecules, particularly in pharmaceuticals and agrochemicals. Its phosphonate group enables the development of enzyme inhibitors, especially for enzymes involving phosphate ester hydrolysis. Commonly employed in the preparation of analogs of amino acids and nucleotides, which show potential in antiviral and anticancer research. Also utilized in coordination chemistry as a ligand for metal complexes due to its amine and phosphonate functionalities. Its bifunctional nature allows for versatile reactivity in organic synthesis, including use in catalysis and material science applications.
