☑ It used in pharmaceuticals.
☑ Cyclen and its derivatives exhibit selective coordination properties for transition metal cations, heavy metal cations, lanthanide and actinide ions, and even for organic or inorganic anions. The accurate behavior of cyclen and its derivatives depends on the properties of its substituents.
☑It is an organic synthesis intermediate, especially a precursor compound for the synthesis of metal ion macrocyclic chelating agents. For example, Cyclen is used to synthesize the contrast agent gadobutrol to perform MRI imaging of the brain and spinal cord, which can accurately determine the exact location of tumors and other lesions. There is great potential in the field of medical research.
