Applicazioni

Tetraethyl methylidenediphosphonate is used in the synthesis of tetrazoloquinoline-based mono- and bisphosphonate esters. It acts as an intermediate for the synthesis of bisphosphonate and bisphosphonic acid derivatives with anticancer and antischistosomal activity. It is also used as a reactant for synthesis of dual substrate-site inhibitors of 3-deoxy-D-arabino-heputosonate 7-phosphate synthase and alpha-amino acid derivatives containing gem-biophosphonates, Lycopene through Wittig-Horner reaction. It is also used as a precursor for the preparation of dendritic polyglycerol anions.

Note

Incompatible with strong oxidizing agents.
