Used primarily in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. It serves as a building block in the development of central nervous system agents due to its structural similarity to neurotransmitters. Commonly employed in the preparation of fluorinated analogs of amphetamines for research purposes, particularly in studying receptor binding and metabolic stability. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving phenethylamine derivatives. Its fluorinated aromatic ring enhances lipophilicity and electron-withdrawing effects, improving drug penetration and resistance to oxidation.
