Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of indole-based bioactive compounds. Its structure supports the creation of more complex molecules with potential antitumor, antimicrobial, or anti-inflammatory properties. Commonly employed in research settings for heterocyclic compound development and in the preparation of fluorescent dyes or sensors due to the electron-withdrawing nitro and chloro groups enhancing photophysical properties. Also utilized in organic synthesis to build functionalized indole scaffolds for drug discovery.
