Used as an intermediate in the synthesis of bioactive indole derivatives, particularly in pharmaceutical research. It serves as a building block for developing compounds with potential antitumor, antiviral, and anti-inflammatory properties. Commonly employed in organic synthesis to introduce the bromoindole moiety, facilitating cross-coupling reactions such as Suzuki or Heck reactions. Also utilized in the preparation of natural product analogs and in medicinal chemistry for structure-activity relationship studies.
