Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated drug candidates where the fluorine atoms enhance metabolic stability and bioavailability. Its aldehyde and hydroxyl functional groups allow for versatile chemical modifications, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of kinase inhibitors and other biologically active compounds in medicinal chemistry research. Also utilized in the design of fluorescent probes due to its aromatic structure and electron-withdrawing fluorine substituents, which can influence photophysical properties.
