Stabilisation of fluorothymidine precursors

摘要

The invention relates to a method for improving stability of radiopharmaceutical precursors, and in particular non radiolabelled nucleoside derivatives which are used as precursors for production of radiolabelled nucleoside derivatives for use in in vivo imaging procedures such as positron emission tomography (PET). The invention further includes formulations of radiopharmaceutical precursors, and cassettes for automated synthesis apparatus comprising the same.
