Description

3-Bromo-5-Methoxy-Benzene-1,2-Diamine is a versatile aromatic diamine derivative, serving as a critical building block in advanced organic synthesis. Its value lies in the strategic positioning of its functional groups—bromo, methoxy, and two amine groups—which enable precise chemical modifications and heterocycle formation. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex heterocyclic compounds, such as benzimidazoles and quinoxalines, which are core structures in various active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides, where the bromine atom allows for further functionalization to tune biological activity.
• Dye and Pigment Manufacturing: Acts as a monomer for producing high-performance polymers and advanced organic dyes, particularly azo dyes, due to its diamine functionality.
• Material Science Research: Employed in the creation of novel organic electronic materials, ligands for metal-organic frameworks (MOFs), and corrosion inhibitors.
• Chemical Research & Development: Serves as a standard or starting material in method development, catalysis studies, and exploring new synthetic pathways in academic and industrial R&D labs.

Quality Control

Our 3-Bromo-5-Methoxy-Benzene-1,2-Diamine is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 nature as an Easily oxidized (store under inert atmosphere) and Light-sensitive (store away from light) compound, it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to air and moisture.
