Introduction | 5-methylsalicylic acid is a salicylic acid derivative. Salicylic acid and its derivatives are commonly found in drugs and natural products, such as sodium bisulfate, metoclopramide tablets, flecainide acetate and so on. In addition, the phenolic hydroxyl group contained in salicylic acid compounds can be easily converted into ether, Ester and other functional groups, and has a good application prospect in organic synthesis. Therefore, the synthesis of salicylic acid compounds has attracted extensive attention. |
Use | 5-methylsalicylic acid is a carboxylic acid derivative and can be used as an organic reagent. |
