Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for active pharmaceutical ingredients due to the presence of reactive functional groups—amine, hydroxyl, and ester—which allow for further chemical modifications. Commonly employed in heterocyclic synthesis, it contributes to the formation of benzoxazole and quinazoline derivatives with biological activity. Also utilized in research settings for developing compounds with potential antimicrobial and antitumor properties. Its chloro and amino groups enable coupling reactions in medicinal chemistry workflows.
