Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require substituted phenethyl frameworks. Its halogenated aromatic structure makes it suitable for coupling reactions and functional group transformations in drug design. Commonly employed in the preparation of kinase inhibitors and anti-inflammatory agents. Also utilized in research settings for the construction of complex organic molecules where a chloro-fluoro substituted ethyl linker is needed.
