碘吡乙酸又名碘锐特(Diodrast),化学名为3,5二碘4-羟基吡啶 N-乙酸,其结构如下:(?)碘吡乙酸的二乙醇胺注射液为临床泌尿系统 X 线诊断造影剂。近些年来国外文献报导,放射性碘吡乙酸用于肾功能的体外测定有一定价值。为了配合临床研究需要及寻找简单而又适宜医院放射性同位素实验室的制备方法,我们进行了标记方法及纯度鉴定的研究。 Iodipamide is also known as Diodrast and its chemical name is 3,5-Diiodo-4-hydroxypyridine N-Acetic acid. Its structure is as follows: (?) Diethanolamine injection of iopamidin for diagnosis of clinical urinary system X-ray Contrast agent. In recent years, foreign literature reports that radioactive iodine and pyridine acetic acid for in vitro determination of renal function has some value. In order to meet the needs of clinical research and find a simple and suitable method for the preparation of the hospital’s radioisotope laboratory, we conducted a labeling method and purity identification.
