Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where the fluorine atom enhances metabolic stability and bioavailability. Its aldehyde group allows for easy functionalization through reactions such as condensation, reduction, or nucleophilic addition, making it valuable in constructing complex molecules. Commonly employed in the preparation of kinase inhibitors and other biologically active compounds in medicinal chemistry. Also utilized in agrochemical research for designing novel pesticides and herbicides due to the electron-withdrawing nitrile and fluorine groups that improve lipophilicity and target binding.
