Used in organic synthesis as an intermediate for pharmaceutical compounds, particularly in the development of indole-based bioactive molecules. Its structure allows for functionalization at multiple sites, making it valuable in the preparation of potential central nervous system agents and receptor ligands. The chlorobutyl chain enables alkylation reactions, while the ester group can be hydrolyzed to form carboxylic acid derivatives for further chemical modifications. Commonly employed in research settings for constructing complex heterocyclic systems with pharmacological interest.
