  A new process for the manufacture of iodinated xanthenes in high purity includes a cyclization step followed by an iodination step. No extraction, chromatographic or solvent concentration steps are required, and the intermediate as well as final compounds are isolated via filtration or similar means. The process requires a single organic solvent, and the steps are completed at temperatures below 100° C. The exclusion of chloride ions, of chloride free-radicals, hypochlorite ions, or hypochlorous acid as reagents or from reagents that may generate these species in situ in the presence of oxidants, prevents undesirable impurity formation. Several new compounds have been conceived and isolated using these methods. These new compounds are also formed into new medicaments.

  一种用于高纯度碘化黄色素制造的新工艺包括一个环化步骤，然后是一个碘化步骤。不需要提取、色谱或溶剂浓缩步骤，中间体和最终化合物均通过过滤或类似手段分离。该工艺需要一种有机溶剂，并且步骤在100°C以下的温度下完成。通过排除氯化物离子、氯自由基、次氯酸根离子或次氯酸作为试剂或从可能在氧化剂存在的情况下生成这些物种的试剂中排除，防止不良杂质形成。使用这些方法已经构思并分离出了几种新化合物。这些新化合物也被制成了新药物。
