7025-19-6,3-(4-Oxo-2-thioxothiazolidin-3-yl)propanoic acid, cas is 7025-19-6, it is a common heterocyclic compound, the thiazolidine compound, its synthesis route is as follows.
Raw material A33 and Rhodamine molar ratio 1:1.1 is dissolved in ethanol, pyridine is added, and reacted at 80 C. for 4 hours. The molar ratio of pyridine to A33 is 1:1. After the reaction was completed, the mixture was cooled to room temperature and a yellow solid precipitated. After suction filtration, the filter cake was washed with dilute hydrochloric acid, washed with water, dried in an infrared light, and then recrystallized from ethanol to obtain a yellow solid with a yield of 82%.
As the rapid development of chemical substances, we look forward to future research findings about 7025-19-6
