The present disclosure relates to a method for labeling a radioisotope includes providing a cyclooctyne compound represented by the following formula (I), and to which a biomolecule, a fluorescent dye, or a nanoparticle compound is bound, and reacting the cyclooctyne compound with a quinone compound represented by the following formula (II) and labeled with the radioisotope in room temperature; a radiolabeling compound represented by the following formula (II), for labeling a molecule having a cyclooctyne moiety; and a composition for medical diagnosis or for treating cancer comprising a quinone compound represented by the following formula (II) and labeled with the radioisotope:
in formula (I), Z is the biomolecule, the fluorescent dye, or the nanoparticle compound,
in formula (II), b is 0 or an integer from 1 to 10; L is CH
2
, —COO—, or —CONH—; M is the radioisotope.
