Description

2-Bromo-3-Methoxypyrazine CAS NO 1209905-41-8 is a versatile halogenated pyrazine derivative, a crucial building block in advanced organic synthesis. Its value lies in its unique structure, which enables the introduction of both bromine and methoxy functional groups into target molecules, facilitating the creation of complex heterocyclic compounds. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and flavor & fragrance industries seeking to develop novel active ingredients and specialty chemicals.

Application

• Pharmaceutical Intermediate: A key synthon in the research and development of novel drug candidates, particularly for central nervous system (CNS) agents and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides, where the pyrazine core contributes to specific biological activity.
• Flavor & Fragrance Chemistry: Serves as a precursor for synthesizing complex aroma compounds, contributing nutty, roasted, or green notes in high-value applications.
• Material Science Research: Employed in the synthesis of organic electronic materials, ligands for catalysis, and other functional organic compounds.
• Cross-Coupling Reactions: The bromine atom makes it an excellent substrate for palladium-catalyzed reactions like Suzuki, Stille, or Negishi couplings for carbon-carbon bond formation.
• Chemical Biology Probes: Useful for creating labeled compounds or molecular probes for studying biological mechanisms.
