Tetrofosmin
Tetrofosmin was developed to overcome the non-target uptake of radioligands by the generation of hetero-atomic compounds. It presents a molecular formula of 1,2-bis(bis(2-ethoxyethyl)phosphino)ethane. Tetrofosmin is part of the group of diphosphines. Tetrofosmin is used in conjunction with technetium Tc-99m as a radiopharmaceutical.
