Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and fungicides, due to its reactive heterocyclic structure. Its chloro group allows for easy substitution, enabling the formation of various derivatives with biological activity. Also employed in the development of pharmaceuticals, where it serves as a building block for compounds with antimicrobial and anti-inflammatory properties. Additionally, it finds use in materials science for designing corrosion inhibitors and functional polymers.
