This invention relates to methods for analyzing radiopharmaceuticals wherein the radiopharmaceutical is derivatized beforehand. This method is suitable for compounds labeled with radioisotope or with cold counterpart e.g. 18F or 19F, compositions comprising such compounds, kits comprising such compounds or compositions and uses of such compounds, compositions or kits for analyzing radiopharmaceuticals. wherein R1 is C(=0)OR6; R2 is C(=0)OR7; R3 is,19F or 18F R4 is hydrogen, Methyl, Ethyl, Propyl. Butyl, t-Butyl or Benzyl; R5 is hydrogen. Methyl, Ethyl, Propyl. Butyl, t-Butyl or Benzyl; R6 is hydrogen, Methyl, Ethyl, Propyl, Butyl, t-Butyl or Benzyl; R7 is hydrogen, Methyl, Ethyl, Propyl. Butyl, t-Butyl or Benzyl; with the proviso that at least one of R4, R5, R6, and R7 is hydrogen
本发明涉及分析放射性药物的方法,其中预先对放射性药物进行衍生化。该方法适用于标记有放射性同位素或冷对应物的化合物,例如18F或19F,包括此类化合物的组合物、包含此类化合物或组合物的试剂盒以及用于分析放射性药物的此类化合物、组合物或试剂盒的用途。其中R1为C(=0)OR6;R2为C(=0)OR7;R3是19F或18F;R4为氢、甲基、乙基、丙基、丁基、叔丁基或苄基;R5为氢、甲基、乙基、丙基、丁基、叔丁基或苄基;R6为氢、甲基、乙基、丙基、丁基、叔丁基或苄基;R7为氢、甲基、乙基、丙基、丁基、叔丁基或苄基;但至少有一个R4、R5、R6和R7为氢。
