摘要:
A radioactive diagnostic agent which comprises a physiologically active substance and a radioactive metallic element combined with a compound of the formula: wherein R I and R 2 are each hydrogen, C 1 -C 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.

摘要:
method of making an organic metal salt or complex is disclosed by reacting a heavy metal hydroxide with an organic Lewis acid or salt thereof in the presence of a form of CO 2 . The reaction may be controlled by the addition of a buffering agent. The method produces organic metal complexes or salts in a pure second salt-free state either in a solution or solid state.
