40161-55-5 - Reference Information
| introduction | 2-bromo-5-fluorotrifluoro-toluene is a colorless liquid under normal temperature and pressure. it is a commercial organic synthon with good solubility in common organic solvents such as methylene chloride, ethyl acetate and dimethyl sulfoxide, but its solubility in water is poor. It can be used as an intermediate in organic synthesis. |
| use | 2-bromo -5-fluorotrifluorotoluene is a light yellow liquid and can be used as an important medicine, pesticide and new liquid crystal material intermediate. For example, it is an important intermediate for the synthesis of anti-tumor drug bicalutamide, bicalutamide is an anti-androgen non-steroidal steroid, it is well tolerated and has no obvious side effects after taking it. With the continuous expansion of the use of 2-bromo-5-fluorotrifluorotoluene, the market demand is also increasing. |
| synthesis method | for the synthesis of 2-bromo -5-fluorotrifluorotoluene, the conventional synthesis method is starting from 3-fluorotrifluorotoluene, and the commonly used brominating reagent is liquid bromine by brominating position 5 of benzene ring under appropriate conditions. According to literature research, the reaction has good regioselectivity and high reaction efficiency. |
