Reference Information
| LogP | 2.79-2.86 |
| biological activity | 3-methylsalicylacid is a salicylic acid derivative that acts on human plasma by activating the fibrinolytic system, and has a significant fibrinolytic activity. |
| Use | This product can be used in the manufacture of azo dyes, especially acid medium bleaching blue B Dye, it can be used as raw material to prepare blue, purple, brown, Green and other triphenylmethane dye more than 20 kinds of media. used as intermediate in organic synthesis and dyes |
| production method | It is produced by solid phase method and solvent method, the latter does not require the treatment of a dry powder of the highly hygroscopic sodium salt of O-cresol. The reaction material is a liquid phase carbon carboxylation reaction, CO2 is completed once, without the need for semi-vapor phenol, can be produced in the ordinary pressure equipment, reducing the use of dehydration and carbon carboxylation equipment. The principle of production is the same for both methods. |
