Regioselective synthesis of DTPA derivatives |
| abstract |
The present invention provides a process for high yield regioselective synthesis of DTPA derivatives that eliminates the need for ion exchange chromatographic separation of intermediates. Moreover, as this process yields a single regioisomer of the chelate, it provides for the regiospecific synthesis of desired chelates useful as radiolabeling agents. |
