摘要:
[OBJECT] The present invention provides an 18 F-labeled azide compound usable in the Huisgen reaction which enables 18 F-labeling although only a small quantity of alkyne compound is available as a counterpart substrate, more specifically the 18 F-labeled azide compound enabling the PET to be applied to peptides or oligonucleotides and enabling the 18 F-labeling of any sites of oligonucleotide other than the 5' end or 3' end thereof, a reagent for 18 F-labeling, and a method for 18 F-labeling of an alkyne compound using the same. [SOLVING MEANS] An 18 F-labeled azide compound according to the present invention is expressed by the following structural formula 1.
