Used in pharmaceutical synthesis as an intermediate for bioactive compounds, particularly in the development of fluorinated drugs where enhanced metabolic stability and membrane permeability are desired. Its trifluoroacetamido group facilitates electron-withdrawing effects, useful in tuning reactivity in heterocyclic systems. Employed in the preparation of nicotinamide-based analogs for potential antiviral or anticancer agents. Also applied in agrochemical research for designing novel active ingredients with improved environmental stability.
