Overview

4-Bromo-3-fluorobenzoic Acid CAS NO. 153556-42-4 is a chemical substance with the molecular formula C7H4BrFO2. It has the appearance of white crystalline powder, density of 1.34, melting point of 207 °C, boiling point of 195.9°Cat760mmHg and flash point of 85 °C. 4-Bromo-3-fluorobenzoic Acid is a chemical substance with the molecular formula C7H4BrFO2. Bromo-3-fluorobenzoic Acid CAS NO. 153556-42-4 is an important pharmaceutical intermediate, which is widely used in the process of drug synthesis.

4-Bromo-3-fluorobenzoic acid CAS NO. 153556-42-4 was prepared by using 4-bromo-3-fluorotoluene as raw material, potassium permanganate as oxidizing agent and sodium fatty alcohol polyether sulfate (AES) as surfactant. The process includes oxidation, filtration, acidification, crystallization, filtration with washing and drying steps. By using surfactant and oxidation at boiling point, the problem of difficult reaction between 4bromotrifluorotoluene and potassium permanganate solution was solved, and the operation process was simplified with high yield.
