Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block for beta-adrenergic receptor ligands due to its structural similarity to known adrenergic modulators. Its fluorinated aromatic ring enhances metabolic stability and membrane permeability, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in research settings to study structure-activity relationships in amide-based bioactive molecules.
