The disclosure provides a compound comprising bisphosphonate functional group and chelating agent. The bisphosphonate functional group part has high affinity for bone tissue, and the chelating agent part has high affinity for metal tracer such as radioisotope. The disclosed compound could be rapidly adsorbed onto the bone surface, and could steady emit ionizing radiation. Therefore, the disclosed compound is suitable for bone scanning technology to find abnormalities in bone.本發明關於一種包括雙膦酸鹽官能基及螯合劑的化合物。雙膦酸鹽官能基部分對於骨組織具有高親和力，且螯合劑的部份對於如放射性同位元元素的金屬示蹤劑具有高親和力。所述化合物能夠快速地被吸附至骨頭表面，並且能夠穩定的釋放電離輻射。因此，本化合物適合用於尋找骨頭中異常處的骨掃描技術。
