Fig. 2From: An efficient preparation of labelling precursor of [11C]L-deprenyl-D2 and automated radiosynthesis(above): semipreparative gamma chromatogram obtained with L-nordeprenyl-D2 free base and (below): same as above but using L-nordeprenyl-D2 hydrochloride salt. Peak in tR = 7.5 min corresponds to [11C]L-deprenyl-D2 Back to article page
