Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective kinase inhibitors. It serves as a building block in medicinal chemistry for creating compounds with potential anticancer and anti-inflammatory activities. Its nitrile and bromo functional groups allow for further chemical modifications, enabling the formation of complex heterocyclic structures. Commonly employed in research settings for designing new bioactive molecules and in the preparation of indole-based derivatives for drug discovery programs.
