How this set was arrived at. base set per Ph. Eur. general monograph 0125 (rule); receptor ligand with a saturable target -> molar activity (rule); organic-phase radiosynthesis assumed from isotope/compound class, no synthesis data confirming it -> GC residual solvents (preliminary); conventional nucleophilic 18F-fluorination assumed from isotope/compound class, no synthesis data confirming K222 use -> Kryptofix test (preliminary)
