Used in organic synthesis, particularly in the production of pharmaceuticals and bioactive compounds. It serves as a key intermediate in the development of indole-based molecules, which are often explored for their potential therapeutic properties. The bromo and acetyl functional groups make it a versatile building block for creating complex structures in medicinal chemistry. It is also employed in research to study the biological activities of indole derivatives, such as anti-inflammatory, anticancer, and antimicrobial effects. Additionally, it is utilized in the synthesis of dyes and other fine chemicals due to its reactive sites.
