Description

3-Amino-4-Bromophenol is a versatile brominated aniline derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both an amino and a hydroxyl group adjacent to a bromine atom, makes it a valuable intermediate for constructing complex molecular architectures. This compound is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty dye sectors for the development of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for targeted therapies.
• Agrochemical Synthesis: Building block for developing advanced herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Used in the production of high-performance, color-fast azo dyes and pigments for industrial applications.
• Polymer Chemistry: Monomer or modifier for creating specialty polymers with enhanced thermal or chemical resistance.
• Liquid Crystal & OLED Materials: Intermediate in the synthesis of electronic chemicals for display and lighting technologies.
• Research & Development: Essential reagent in academic and industrial R&D labs for medicinal chemistry and material science projects.
• Cross-Coupling Reactions: Serves as a substrate in palladium-catalyzed reactions (e.g., Suzuki, Buchwald-Hartwig) for carbon-heteroatom bond formation.

Quality Control

Every batch of 3-Amino-4-Bromophenol is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency that meets the stringent requirements of synthesis and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, 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, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
