  • Publication number: 20220017433
    Abstract: The invention relates to a method for labeling a target compound with a radiometal by photochemically induced conjugation. Furthermore, a chelating compound for use in said method is provided. The chelating compound is characterized by an arylazide moiety which can be photo-conjugated to a target compound and a chelator moiety which can be radiolabelled. The photo-conjugation and radiolabelling are both performed at basic pH performed in a simultaneous one-pot reaction.
