Radio-HPLC analysis of [11C]CH3I, [11C]CH3OTf and crude reaction mixture. The individual peaks were identified by co-injection of commercially available unlabelled reference compounds. The analyzed [11C]CH3OTf batch contained approximately 13% of [11C]CH3I due to incomplete conversion of [11C]CH3I into [11C]CH3OTf. [11C] methanol originates from the reaction of [11C]CH3OTf with water. A similar phenomenon was seen for the crude reaction mixture
