Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. Its reactive acyl chloride group enables it to form amide and ester bonds, making it valuable in constructing complex molecules. Commonly employed in the production of herbicides and fungicides due to the presence of fluorine atoms, which enhance bioavailability and metabolic stability. Also utilized in the development of active pharmaceutical ingredients (APIs) where fluorinated aromatic structures are needed for optimal biological activity. Its selectivity and reactivity make it suitable for controlled reactions in multi-step organic syntheses.
