Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with anti-inflammatory and analgesic properties. It plays a role in constructing pyrazole-based drug candidates due to its reactive nitrogen and chlorine sites, which allow for further functionalization. Commonly employed in agrochemical research for designing herbicides and insecticides, where the methyl and chloro substituents enhance bioactivity and stability. Also utilized in the preparation of dyes and functional materials where heterocyclic frameworks improve performance under thermal or oxidative stress.
