Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure supports the construction of complex indole-based molecules that exhibit biological activity. It is also employed in research settings for the preparation of analogs in medicinal chemistry programs targeting neurological disorders. Additionally, it serves as a building block in the creation of agrochemicals and bioactive molecules where indole scaffolds are required for activity.
