Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its reactivity allows for the formation of amide and ester derivatives, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Also employed in the preparation of indole-based compounds with potential antitumor, antiviral, or anti-inflammatory activity. Commonly utilized in research settings for library generation in drug discovery programs.
