Description

5-Bromo-2,3-diaminofluorobenzene is a high-purity fluorinated aromatic diamine building block of significant importance in advanced organic synthesis. Its value lies in the strategic placement of reactive amino and halogen groups adjacent to a fluorine atom, enabling the construction of complex heterocyclic and pharmaceutical scaffolds. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors for developing novel active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of fluorinated benzimidazole, quinoxaline, and other nitrogen-containing heterocycles with potential biological activity.
• Agrochemical Synthesis: Used in the research and development of new-generation herbicides and fungicides that incorporate fluorine for enhanced efficacy and environmental profile.
• Material Science: Serves as a monomer or cross-linking agent in the production of specialized polymers, such as polyimides and epoxy resins, for high-performance applications.
• Ligand and Catalyst Development: Employed to create novel chelating ligands for metal catalysts used in asymmetric synthesis and coupling reactions.
• Fluorescent Dye and Sensor Chemistry: Acts as a core structure for developing fluorophores and molecular probes used in bio-imaging and diagnostic assays.
• Academic and Contract Research: Essential for methodological studies and custom synthesis projects in organic and medicinal chemistry laboratories worldwide.

Quality Control

Our 5-Bromo-2,3-diaminofluorobenzene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and mass spectrometry, to ensure it meets the high standards required for research and production. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
