近年来,标记药物的示踪研究,在工、农、医各个领域应用广泛,其标记方法结合典型标记化合物的制备,主要介绍定位同位素标记的方法: 1、定位催化交换反应、通过氚氢或硫—35硫的交换。
In recent years, tracer studies of labeled drugs have been widely used in various fields of industry, agriculture and medicine. The labeling methods combined with the preparation of typical labeled compounds mainly introduce the methods of positioning isotope labeling: 1. Locating the catalytic exchange reaction through tritium hydrogen or Sulfur-35 sulfur exchange.
