| use | 3, 5-diiodosalicylic acid is a metabolite of aspirin (A187780) and an anti-inflammatory, anti-platelet and cancer preventive agent. 3, 5-diiodosalicylic acid showed agonist activity on the orphan G protein-coupled receptor GPR35. Used as an iodine source for food. Also used as a pharmaceutical intermediate. |
| production method | dissolve salicylic acid in glacial acetic acid, add a solution prepared by iodine monochloride and glacial acetic acid, add water, and react at 80 ℃ for 20min. After the reaction, the product was cooled, filtered out, and refined to obtain 3, 5-diiodosalicylic acid with a yield of 91-92%. |
