Used in the synthesis of pharmaceutical intermediates, particularly in the development of antiparasitic and antiviral agents. It serves as a key building block in the preparation of certain benzimidazole-derived drugs, which exhibit biological activity by interfering with nucleic acid synthesis in pathogens. Also employed in research settings for designing novel compounds with potential antimicrobial properties. Its chlorinated structure enhances reactivity in coupling reactions, making it valuable in medicinal chemistry and agrochemical development.
