Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of neonicotinoid insecticides. It serves as a building block for compounds with biological activity due to the presence of reactive chlorine and carboxylic acid groups. Its derivatives are explored for antimicrobial, antifungal, and antiviral properties. Also employed in the development of functional materials and specialty chemicals where heterocyclic scaffolds enhance performance.
