Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antidepressant drugs. It serves as a building block in organic reactions where the aldehyde group enables the formation of carbon-carbon bonds, while the fluorine and methoxy substituents influence electronic and steric properties to enhance drug potency and metabolic stability. Commonly employed in the preparation of bioactive molecules and fine chemicals requiring specific substitution patterns on aromatic rings.
