2-Bromo-5-Fluorobenzoic - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| introduction | 2-bromo-5-fluorobenzoic acid has a melting point of 154 degrees to 157 degrees, and its solubility in water is poor, and its appearance is white to light yellow crystal powder under normal temperature and pressure. |
| Uses | 2-bromo-5-fluorobenzoic acid is a common organic synthesis intermediate. The main purpose is to use the bromine atom on the benzene ring, The fluorine atom is transformed into the molecular structure of the target. For example, the bromine atom can be coupled by Suzuki, introducing an aromatic ring or alkyl chain; or converting the bromine atom into boric acid or boric acid ester, and then using the ability of boric acid ester to transform the complex molecule Synthesis. Fluorine atoms can also undergo a series of transformations including aromatic nucleophilic substitution reactions and so on. Finally, the carboxyl group on the benzene ring can be easily converted into amide, ester group, Webamide and so on. |
| Synthesis method | Through the oxidation reaction of 2-bromo-5-fluorobenzaldehyde, the aldehyde group is oxidized to the corresponding carboxyl group. The commonly used oxidant is potassium permanganate and oxygen oxidation promoted by metal. |
| environmental hazards | 2-bromo -5-fluorobenzoic acid, as a halogen-containing organic compound, is more harmful to the water environment and cannot allow undiluted or large amounts of products to contact groundwater, waterways or sewage systems. |
