Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the development of bioactive molecules due to its nitro and chloro functional groups. Commonly employed in the preparation of indole-based compounds with potential antitumor, antimicrobial, or anti-inflammatory properties. Also utilized in research settings for the synthesis of fluorescent probes and dyes, leveraging the indole scaffold’s favorable photophysical characteristics.
