Used as a key intermediate in the synthesis of biologically active indole derivatives, particularly in pharmaceutical research. Its structure allows for selective functionalization at the 4-position, making it valuable in the development of potential drug candidates targeting inflammation, cancer, and central nervous system disorders. The bromo group facilitates cross-coupling reactions such as Suzuki or Heck reactions, enabling the construction of complex molecules. Also employed in agrochemical research for designing new active ingredients due to its stability and reactivity profile.
