Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and fungicides. Its fluorinated aromatic structure enhances metabolic stability and bioavailability in active compounds. Commonly employed in the development of selective kinase inhibitors and other biologically active molecules. Also utilized in the preparation of dyes and specialty polymers where thermal and chemical resistance are required. The hydrochloride salt form improves handling stability and solubility in aqueous reaction systems.
