1-chloro-3-Methyl-Pyrrolo[1,2-a]pyrazine

1-Chloro-3-methylpyrrolo[1,2-a]pyrazine (CAS: 1025054-90-3) is a heterocyclic chlorinated compound containing a pyrrolo[1,2-a]pyrazine core with a chlorine substituent. It is mainly used as an intermediate in pharmaceutical and agrochemical synthesis, especially in the development of bioactive molecules—such as antiviral, antibacterial, and anticancer agents—featuring the pyrrolo-pyrazine scaffold. The chlorine atom serves as a reactive site for nucleophilic substitution, enabling the introduction of diverse functional groups during lead optimization.
