Used as a key intermediate in the synthesis of sulfa drugs, particularly sulfamethoxypyridazine, an antibacterial agent. Its structure enables coupling with sulfonamide components, enhancing antimicrobial activity. Also employed in research for developing new heterocyclic compounds with potential pharmaceutical applications. Shows utility in agrochemicals as a building block for certain herbicides and plant growth regulators. Its methylthio and amino groups allow for further chemical modifications, making it valuable in medicinal chemistry for creating novel drug candidates.
