We report the use of DOTA as a chelator for titanium. The resulting complex is fully characterised and stability studies reveal its high kinetic inertness against transmetallation and transchelation. The radiolabeling of DOTA with Ti, a guaiacol-based liquid-liquid extraction method, leads to a high radiochemical conversion up to 98%.
我们报告了 DOTA 作为钛螯合剂的用途。所得配合物得到了充分的表征，稳定性研究表明其具有很高的动力学惰性，不易发生转金属和转螯合反应。用 Ti 通过基于愈创木酚的液-液萃取方法对 DOTA 进行放射性标记，可获得高达 98%的高放射化学转化率。
