Used as an intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of indole-based drugs. Its nitro group allows for further functionalization, such as reduction to an amine, enabling the construction of complex molecules in medicinal chemistry. Commonly employed in research settings for the preparation of substituted indoles, which are key scaffolds in drug discovery for anticancer, anti-inflammatory, and neurological agents. Also utilized in organic synthesis to protect the indole nitrogen during multi-step reactions, ensuring selective modification at other reactive sites.
