Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where fluorine substitution enhances metabolic stability and bioavailability. Its aldehyde and amine functional groups allow for versatile reactivity, enabling Schiff base formation or reductive amination, which are common steps in drug construction. Also employed in the preparation of agrochemicals and specialty dyes due to its electron-withdrawing fluorine atoms and aromatic scaffold, which contribute to improved photostability and reactivity selectivity.
