  • Method for purification of 18F-labeled choline analogues
    Patent number: 9839702
    Abstract: The present invention relates to a method for purification of 18F-labeled choline analogs in a solution injectable to a patient, prepared using non-gaseous synthesis paths, comprising a step of solid phase extraction (SPE) purification using a solid support, wherein the solid support used in the solid phase extraction purification has the characteristic to retain impurities and reagents from the solution but not the 18F-labeled choline analogs.
    Type: Grant
    Filed: June 2, 2014
    Date of Patent: December 12, 2017
    Assignee: Trasis S.A.
    Inventors: Jean-Luc Morelle, Muhammad Otabashi, Gauthier Philippart, Samuel Voccia
  • Stabilization of radiosynthetic intermediates
    Patent number: 9796641
    Abstract: The present invention relates to a method for stabilizing radiosynthetic intermediates used in synthesis of 18F radiolabeled aromatic amino acid derivatives toward decomposition caused by beta and gamma radiations by the use of radical scavengers and/or reductants and/or antioxidants.
    Type: Grant
