2-溴-4-氟苯并三氟化 - Introduction
It is an organic compound with the chemical formula C7H3BrF4. It is a colorless to pale yellow liquid with a special odor at room temperature.
Nature:
1. melting point:-33 ℃
2. Boiling point: 147-149 ℃
3. density: 1.889g/cm³
4. Solubility: Soluble in organic solvents such as ether, ethanol and dichloromethane, insoluble in water.
Use:
It is mainly used as an intermediate in organic synthesis. It is commonly used in drug synthesis, chemical catalysis and organic materials, such as benzopyrazolones, cyclic macrocyclization, organic photoelectric materials synthesis, etc.
Preparation Method:
The preparation method of calcium is mainly through the reaction of bromobenzene and trifluorotoluene under appropriate conditions. Usually, bromobenzene reacts with trifluorotoluene in the presence of copper powder or cuprous under heating to form fluorotoluene.
Safety Information:
It is irritating and should avoid direct contact with skin and eyes. Personal protective equipment such as protective gloves, goggles and protective clothing should be worn during use and handling. Avoid inhaling its vapors and make sure to operate in a well-ventilated place. In addition, it should be stored in a sealed container, away from heat and fire sources.
