Used primarily in the synthesis of pharmaceuticals, particularly in the development of compounds with potential therapeutic effects. It serves as a key intermediate in the production of indole-based drugs, which are often explored for their biological activities, including anti-inflammatory, anticancer, and antimicrobial properties. Additionally, it is utilized in organic chemistry research to create novel indole derivatives for studying structure-activity relationships in drug discovery. Its role in the preparation of complex molecules makes it valuable in medicinal chemistry and pharmacological studies.
