Description

3-Fluoro-4-Bromoaniline is a halogenated aniline derivative that serves as a versatile and critical building block in advanced organic synthesis. Its unique structure, featuring both fluorine and bromine substituents, makes it a valuable intermediate for constructing complex molecules with tailored electronic and steric properties. This compound is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries for the development of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring fluorinated and brominated aromatic systems.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the fluorine atom can enhance biological activity and metabolic stability.
• Material Science: Serves as a monomer or functionalization agent in the development of specialty polymers, liquid crystals, and organic electronic materials.
• Chemical Research: Employed in academic and industrial R&D for cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig) to create novel chemical entities.
• Dye and Pigment Industry: Acts as an intermediate for synthesizing complex, halogenated dyes and pigments.

Quality Control

Our 3-Fluoro-4-Bromoaniline is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) with detailed specifications are provided to guarantee traceability, consistency, and reliability for your critical processes.

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 tightly sealed after opening to prevent degradation. Keep away from incompatible materials such as strong oxidizing agents.
