Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of indole-based derivatives with potential antitumor, antimicrobial, and anti-inflammatory properties. Its hydrazide functional group allows for easy modification to form hydrazone derivatives, which are explored for their biological activity. Also employed in the design of enzyme inhibitors due to the indole scaffold’s affinity for various biological targets. Shows promise in medicinal chemistry for creating new therapeutic agents.
