Oxabiphor (Oxabifor) acid is a chelator for the lanthanide tetraphosphonate complexes synthesis. Oxabiphor (oxa-bis-ethylenenitrile tetra(methylene phosphonic acid); oxybis(ethylene)bis(nitrilobismethylene)tetrakisphosphonic acid) is useful for the radionuclides delivery due to complexation properties [1].
