3-Bromo-2-fluorobenzoic acid is used as a reagent to synthesize Dabrafenib, an inhibitor of BRAF kinase that is used to treat BRAF V600-mutation positive carcinoma. BRAF is a gene that mediates cell growth and is activated by mutations caused by cancer. 3-Bromo-2-fluorobenzoic acid is also used as a reagent to prepare Alkynlphenoxyacetic acid receptor agonists, compounds that can be potentially used for the treatment of allergic inflammatory diseases (such as allergic rhinitis).
