Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) containing pyrazine rings. Its reactive chloromethyl group allows for easy alkylation and coupling reactions, making it valuable in constructing complex drug molecules. Commonly employed in the production of antiviral, antibacterial, and antifungal agents. Also utilized in agrochemical synthesis for creating novel pesticides and herbicides due to its ability to enhance bioavailability and stability in final compounds. Suitable for use in research settings for developing new heterocyclic compounds.
