Abstract:
The present disclosure relates to a composition for stabilizing the radiochemical purity of [ 18 F]fluoro-dopa by inhibiting the formation of impurities during a predetermined time period, and a method for preparing the same. The composition according to the present disclosure includes: [ 18 F]fluoro-dopa; ethanol in a concentration of 5% to 30%(v/v) relative to the total composition; and a buffer having a pKa value of 6 to 8.1 at 25° C., in which the composition stabilizes the radiochemical purity of the [ 18 F]fluoro-dopa by inhibiting the formation of impurities during a predetermined time period.

Claim (Index 2):
The composition according to  claim 1 , wherein the composition exhibits a radiochemical purity of at least 90% by inhibiting the formation of impurities for 2 to 6 hours after synthesis of the [ 18 F]fluoro-dopa at a pH of 6 to 8.
