Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of anticoagulant and anti-inflammatory agents. It serves as a building block for introducing the 4-fluorophenyl moiety into more complex molecules, enabling the development of active drug substances. Its reactivity makes it valuable in organic transformations such as nucleophilic substitution and condensation reactions. Also utilized in the preparation of heterocyclic compounds for medicinal chemistry research.
