Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It serves as a key reagent in the formation of benzimidazoles, which are structural motifs in various bioactive molecules, including antiparasitic and antiviral agents. Its reactivity allows for efficient alkylation and cyclization reactions, making it valuable in medicinal chemistry for constructing nitrogen-containing rings. Commonly employed in the development of kinase inhibitors and other drug candidates due to its ability to facilitate carbon-nitrogen bond formation under mild conditions.
