Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in creating compounds with antitumor, antiviral, and anti-inflammatory activities. Commonly employed in medicinal chemistry for building complex heterocyclic systems through cross-coupling and nucleophilic substitution reactions. Also utilized in the preparation of fluorinated analogs to improve metabolic stability and binding affinity in drug candidates.
