Used as a chelating agent in radiopharmaceuticals, particularly for stabilizing metal ions like gallium-68, copper-64, or lutetium-177 in targeted imaging and cancer therapy. Its structure allows for efficient conjugation to biomolecules such as peptides or antibodies, enabling precise delivery to tumor cells. The tert-butoxy groups enhance solubility and stability during radiolabeling and in biological environments. Commonly applied in PET imaging and targeted radionuclide therapy due to its high selectivity and in vivo stability.
