A Process for the preparation of 5-bromo-2,4-difluorobenzoic acid 5-Bromo-2,4-difluorobenzoic acid is an important intermediate in the agrochemical and pharmaceutical industry. In the present disclosure 5-bromo-2,4-difluorobenzoic acid is prepared from 2,4-difluorobenzonitrile using a brominating agent in the presence of aqueous sulfuric acid in a simple, efficient and environmentally friendly process. Br 5-Bromo-2,4-difluorobenzoic acid (I) 5-bromo-2,4-difluorobenzoic acid is obtained in high yield with purity in the range of 93% to 99%. |
