Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of indole-based drugs targeting neurological and inflammatory conditions. Its structure allows for selective modification in medicinal chemistry, making it valuable in creating serotonin receptor modulators. Also employed in research settings to design enzyme inhibitors and bioactive molecules with potential anticancer properties. The sulfonyl and ester groups enhance solubility and reactivity, facilitating coupling reactions in multi-step organic syntheses.
