    摘要: The present invention relates to a process for the preparation of specifically labelled TTX of high specific activity. In the present process, TTX is oxidized by use of the Pfitzer-Moffat method or Fenton's reagent and the aldehyde obtained is hydrated. The hydrated aldehyde is reduced with alkali metal o alkaline earth metal borotritide. The radioactive TTX so obtained, quite surprisingly, has a specific activity many times greater than previously prepared radioactive TTX.
