Application
2-Chloropyrazine (CAS 14508-49-7) is a versatile heterocyclic building block serving as a critical intermediate in pharmaceutical, agrochemical, and fine chemical synthesis. The chlorine atom at the 2-position acts as an excellent leaving group, enabling nucleophilic aromatic substitution (SNAr) reactions to efficiently introduce diverse nucleophiles, constructing complex molecular architectures. In medicinal chemistry, it is instrumental in developing APIs, particularly pyrazinamide analogs for tuberculosis therapy and other nitrogen-containing heterocycles targeting CNS disorders and oncology. The compound is also used to prepare hetaryloxy benzoxaboroles with antimalarial activity and serine β-lactamase inhibitors. In agrochemistry, it is utilized to produce herbicides, insecticides, and fungicides with enhanced targeting efficacy. Additionally, 2-chloropyrazine serves as an electrolyte additive in lithium-sulfur battery research.
