Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where the fluorine atoms enhance metabolic stability and bioavailability. Its aldehyde group allows for easy functionalization, making it valuable in constructing complex molecules. Commonly employed in the preparation of kinase inhibitors and other biologically active compounds in medicinal chemistry research. Also utilized in agrochemical synthesis for creating herbicides and fungicides with improved efficacy and environmental profiles.
