Used as a key intermediate in the synthesis of thiazine-based pharmaceuticals, particularly in the development of central nervous system agents and anti-inflammatory compounds. Its nitrile and ketone functional groups allow for versatile chemical modifications, enabling the formation of heterocyclic structures important in drug design. Commonly employed in research settings to build fused ring systems that exhibit biological activity, including potential anticonvulsant and antimicrobial properties. Also utilized in agrochemical research for developing novel pesticide candidates due to its stable aromatic backbone and reactivity profile.
