Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of serotonin receptor modulators. Its trifluoromethoxy group enhances metabolic stability and membrane permeability, making it valuable in optimizing drug candidates for central nervous system disorders. Also employed in agrochemicals for designing novel pesticides with improved efficacy and environmental profile. Commonly found in research settings for structure-activity relationship studies involving indole derivatives.
