The (YCl3)-Y-90 radionuclide precursor (solution of Y-90(3+) in diluted HCl) of high purity and high specific activity is already commercially produced and successfully used in nuclear medicine. At the Nuclear Physics Institute ASCR, the (YCl3)-Y-90 radionuclide precursor is prepared using extraction (SrY)-Sr-90-Y-90 generator (technology of centrifuge extractors with di-2-ethylhexylphosphoric acid, D2EHPA).(1) Its radionuclidic, radiochemical, and chemical purity were examined and specified. The procedure developed for labeling of DOTA-Tyr(3)-octreotide (DOTATOC) with carrier-free Y-86/90 by ROSCH2 at the Institute of Nuclear Chemistry of the University Mainz was optimized and modified in our Department of Radiopharmaceuticals at NPI ASCR as standard labeling test (SLT) for analytical purposes. The SLT as a method for (YCl3)-Y-90 radionuclide precursor quality control determining its labeling efficiency using ITLC SG chromatography is described and proposed thereinafter.
