Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring selective substitution on aromatic rings. Its functional groups—chloro, nitro, and hydroxyl—allow for sequential reactions, enabling the construction of complex molecules. Commonly employed in the preparation of herbicides and fungicides due to its reactivity and stability under various transformation conditions. Also utilized in research settings for the development of fluorescent probes and labeling reagents, where the nitro group acts as a quenching moiety. Its versatility in nucleophilic substitution and reduction reactions makes it valuable in multi-step organic syntheses.
