Regio-selective synthesis of dtpa derivatives |
| abstract |
Invention Patent: "REGIO-SELECTIVE SYNTHESIS DEDIVATED FROM DTPA". The present invention relates to a process for regio-selective synthesis of high production of DTPA derivatives which eliminates the need for chromatographic separation of ion exchange from intermediates. In addition, since this process produces a regio-isomer of the chelate, it provides the regio-specific synthesis of the desired chelates useful as radiolabeling agents. |
