Description

2,3-Dibromo-Quinoxaline is a halogenated heterocyclic organic compound with the CAS number 23719-78-0, serving as a versatile and critical building block in advanced chemical synthesis. Its value lies in its high reactivity as a brominated intermediate, enabling precise functionalization for creating complex molecular architectures. This product is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and material science industries who require reliable, high-purity intermediates for their synthetic pathways.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with quinoxaline-based pharmacophores.
• Agrochemical Synthesis: Used in the development of novel fungicides, herbicides, and insecticides where the dibromoquinoxaline moiety imparts specific biological activity.
• Organic Light-Emitting Diodes (OLEDs): Acts as a building block for electron-transport materials and host materials in OLED displays and lighting due to its electron-deficient quinoxaline core.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized nitrogen-containing ligands used in transition metal catalysis.
• Material Science Research: Employed in the creation of novel polymers, dyes, and pigments with tailored electronic or optical properties.
• Cross-Coupling Reactions: A valuable substrate for palladium-catalyzed reactions like Suzuki, Stille, or Buchwald-Hartwig amination, allowing for diverse derivatization.

Quality Control

Our 2,3-Dibromo-Quinoxaline is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from heat and incompatible materials. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
