Description

4-(4-Aminophenyl)-2-Bromo-Aniline is a high-purity, bifunctional aromatic amine intermediate featuring both a primary amine and a bromine substituent on its molecular scaffold. This unique structure makes it a critical building block for synthesizing complex organic molecules, particularly in advanced material science and pharmaceutical research. It is essential for manufacturers and R&D laboratories developing high-performance polymers, liquid crystals, and active pharmaceutical ingredients (APIs) where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, especially those targeting central nervous system (CNS) disorders and oncological treatments.
• Advanced Polymer Synthesis: Used in the production of high-performance polyimides and aramids, imparting thermal stability and mechanical strength to specialty plastics and fibers.
• Liquid Crystal Materials: Acts as a core component in the manufacture of liquid crystal displays (LCDs) and other electro-optical devices.
• Agrochemical Synthesis: Employed in creating advanced herbicides and pesticides with specific activity profiles.
• Dye and Pigment Manufacturing: Functions as an intermediate for producing azo dyes and other complex colorants.
• Cross-coupling Reactions: The bromine moiety makes it a valuable substrate for palladium-catalyzed reactions like Suzuki and Buchwald-Hartwig couplings, enabling complex molecular assembly.
• Research & Development: A valuable tool for academic and industrial chemists exploring new synthetic pathways and material properties.

Quality Control

Our 4-(4-Aminophenyl)-2-Bromo-Aniline is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for sensitive synthetic applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

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