Used as a chelating agent in radiopharmaceuticals, particularly for stabilizing metal ions like gallium-68, copper-64, or lutetium-177 in diagnostic and therapeutic applications. Its structure allows for strong, selective binding of metal ions, making it valuable in PET imaging and targeted radiotherapy. The compound’s multiple tert-butyl and acetyl groups enhance lipophilicity and stability, improving in vivo performance. It is also employed in bioconjugation, where it links radionuclides to targeting molecules such as peptides or antibodies for precise tumor detection and treatment.
