API Description: Lutetium-177 is used as an active pharmaceutical ingredient (API) in the manufacture of therapeutic radiopharmaceuticals. Supplied typically as lutetium-177 chloride (¹⁷⁷LuCl₃), it serves as a radioactive precursor that is chemically bound to targeting molecules such as peptides or antibodies. Once administered, the beta radiation emitted by Lu-177 delivers localized cytotoxic effects to diseased cells (e.g., tumor cells), making it a key API in targeted radionuclide therapy products.
