Description

7-Bromo-1-Methyl-1H-Quinoxalin-2-One is a high-purity brominated quinoxalinone derivative, serving as a critical synthetic intermediate in advanced organic chemistry. Its value lies in providing a functionalized, heterocyclic scaffold essential for constructing complex molecules with targeted biological or material properties. This compound is primarily needed by research institutions and pharmaceutical companies engaged in medicinal chemistry, agrochemical development, and the synthesis of novel functional materials.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of potential drug candidates, particularly those targeting kinase inhibition or other heterocycle-dependent biological pathways.
• Agrochemical Research: Used in the development of new herbicides, fungicides, or insecticides where the quinoxalinone core contributes to biological activity.
• Material Science: Serves as a precursor for organic electronic materials, such as ligands for metal-organic frameworks (MOFs) or components in organic semiconductors.
• Chemical Biology: Utilized as a probe or tag in biochemical research due to its bromine handle for further functionalization via cross-coupling reactions.
• Academic & R&D Synthesis: A valuable reagent for methodological development in organic synthesis, including palladium-catalyzed coupling reactions.
