Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of bioactive molecules, particularly in the development of serotonin receptor modulators and kinase inhibitors. Commonly employed in research settings for the synthesis of indole-based compounds with potential antitumor, antiviral, and anti-inflammatory activities. Also utilized in the fabrication of functional materials and in medicinal chemistry for structure-activity relationship studies.
