Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for indole-based derivatives that exhibit potential antitumor, antiviral, and kinase inhibitory activities. Commonly employed in the development of small molecule drugs targeting cancer pathways, especially in the design of tyrosine kinase inhibitors. Also utilized in agrochemical research for the creation of novel active ingredients due to its structural compatibility with bioactive molecules. Its bromo functionality allows for further cross-coupling reactions, enhancing its utility in medicinal chemistry.
