Sodium 2-fluorobenzoate is primarily used in organic synthesis as a building block for more complex chemical compounds. It is often employed in the pharmaceutical industry for the development of active pharmaceutical ingredients (APIs), particularly in the synthesis of fluorinated aromatic compounds. Its fluorine atom enhances the biological activity and metabolic stability of the resulting molecules, making it valuable in drug design. Additionally, it serves as a precursor in the production of agrochemicals, where fluorinated compounds are utilized for their enhanced efficacy and specificity. In research, it is used as a reagent in various chemical reactions, including nucleophilic substitution and coupling reactions, due to its reactivity and stability.
