2905-82-0 - Introduction
Methyl 5-methoxysalicylate is an organic compound with the formula C9H10O4, which contains a methoxy group and a methyl ester group. It is a colorless to pale yellow liquid at room temperature.
methyl 5-methoxysalicylate is mainly used as a spice ingredient, with wood, flower, fruit and other odor characteristics. It can be added to perfumes, soaps, shampoos and other products to increase the aroma.
Methyl 5-methoxysalicylate can be prepared in a variety of ways. One commonly used method is the esterification of salicylic acid with methanol. First, salicylic acid and methanol are mixed, and then an appropriate amount of acidic catalyst (such as sulfuric acid or ammonium sulfate) is added, and the reaction is carried out at an appropriate temperature and reaction time. After the completion of the reaction, the pure methyl 5-methoxysalicylate product can be obtained by distillation and other methods.
Regarding safety information, methyl 5-methoxysalicylate is generally considered to be a relatively safe compound, but the following should be noted:
-It may be irritating to the eyes and skin, so avoid contact when using it. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical assistance if necessary.
-In use, should follow the correct laboratory procedures, avoid inhalation of its vapor. The work area should be well ventilated.
-This compound may be toxic to aquatic organisms, so local environmental regulations need to be followed when disposing of waste.
