The Radiolabeling of a Gly-Sar Dipeptide Derivative with Flourine-18 and Its Use as a Potential Peptide Transporter PET Imaging Agent

Molecules, 2020
We have developed a novel fluorine-18 radiotracer, dipeptide 1, radiolabeled in two steps from mesylate 3. The initial radiolabeling is achieved in a short reaction time (10 min) and purified through solid-phase extraction (SPE) with modest radiochemical

Production of Fluorine-18 by Small Research Reactor [PDF]

Journal of Nuclear Science and Technology, 1967
High purity 18F was prepared by irradiating 1 g of lithium hydroxide or otherwise 0.14 g of enriched lithium carbonate containing 50% 6Li in the pneumatic tube of a TRIGA-II research reactor at a thermal neutron flux of 1.2×1012 n/cm2-sec. After cooling for 20 min, the irradiated lithium hydroxide was dissolved in distilled water. The resulting 13F was
