Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial and carbonic anhydrase inhibitory activity. It serves as a building block in medicinal chemistry for creating compounds targeting glaucoma, epilepsy, and bacterial infections. Its chlorinated thiophene core enhances reactivity for further functionalization in drug design. Also explored in agrochemicals for its potential in developing new herbicides and plant growth regulators.
