Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective kinase inhibitors and anti-inflammatory compounds. Its structure supports derivatization for targeting specific enzyme pathways, making it valuable in medicinal chemistry research. Commonly employed in the preparation of indole-based drug candidates due to its reactive ester group and halogen substitution pattern, which facilitate further chemical modifications. Also utilized in the study of serotonin receptor analogs owing to the indole core's biological relevance.
