A radioactive diagnostic agent which comprises a physiologically active substance and a radioactive metallic element combined with a compound of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are each hydrogen, C.sub.1 -C.sub.3 alkyl or phenyl. The agent is characteristic in having a high stability even after being administered into a human body and showing the substantially the same behavior as the physiologically active substance itself in a human body.
一种放射性诊断剂,包括生理活性物质和与化合物结合的放射性金属元素,该化合物的公式为:##STR1##其中R.sup.1和R.sup.2分别为氢、C.sub.1-C.sub.3烷基或苯基。该剂具有高稳定性,即使在人体内使用后仍保持高稳定性,并在人体内表现出与生理活性物质本身基本相同的行为。
