Description

3-Bromo-5-Methoxyaniline is a versatile aromatic amine derivative, serving as a critical building block in advanced organic synthesis. Its value lies in the strategic positioning of bromine and methoxy substituents on the aniline ring, enabling selective functionalization and the construction of complex molecular architectures. This intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to develop active ingredients, functional materials, and dyes.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds targeting central nervous system disorders.
• Agrochemical Synthesis: Building block for developing novel herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Used in the production of azo dyes and other complex colorants for textiles and plastics.
• Liquid Crystal & OLED Materials: Intermediate for creating charge-transport materials and emissive layers in electronic displays.
• Polymer Modification: Functional monomer for introducing aromatic amine groups into polymer chains to alter thermal or electronic properties.
• Cross-Coupling Reactions: Serves as a substrate in Buchwald-Hartwig amination and other palladium-catalyzed coupling reactions.
• Research & Development: Valuable reagent in academic and industrial R&D for exploring new synthetic pathways and heterocyclic compounds.

Quality Control

Our 3-Bromo-5-Methoxyaniline is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment. We support compliance with REACH and other global regulatory frameworks.

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.
