Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of benzimidazole-based drugs. It plays a key role in creating compounds with antiparasitic, antiviral, and anticancer activities. Its reactive bromomethyl group allows for easy alkylation, making it valuable in constructing complex molecules in medicinal chemistry. Commonly employed in research settings to develop proton pump inhibitors and anthelmintic agents. Also utilized in the preparation of functionalized benzimidazole derivatives for use in agrochemicals and materials science.
