Abstract:In the preparation of broad spectrum antibiotic medicine Florfenicol, there are two main impurities. In this paper, the structures of two impurities were analyzed with proposed reaction mechanism. The two impurities were synthesized and characterized by 1H NMR and HRMS, which were confirmed to be thiamphenicol and 2-chloro-N-((1S,2R)-1-fluoro-3-hydroxy-1-(4-(methylsulfonyl)phenyl)propan-2-yl)acetamide. This study provided a necessary basis for the optimization of the synthesis process of Florfenicol, improvement of product quality and full-component analysis.
Key words:Florfenicol; thiamphenicol; 2-chloro-N-((1S,2R)-1-fluoro-3-hydroxy-1-(4-(methylsulfonyl)phenyl)propan-2-yl)acetamide
