Description

1,4-Benzenediamine, N1,N1,N4,N4-Tetrakis(4-Bromophenyl)- is a high-purity, multi-brominated aromatic amine derivative that serves as a critical advanced intermediate in organic synthesis. Its value lies in its unique molecular architecture, featuring a central phenylenediamine core symmetrically functionalized with four electron-withdrawing bromophenyl groups, making it an essential building block for creating complex, functional materials. This compound is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel active ingredients and high-performance polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of potential drug candidates, particularly those targeting central nervous system disorders, due to its ability to modulate pharmacokinetic properties.
• Agrochemical Synthesis: Serves as a key precursor for developing novel herbicides and fungicides, where the bromine atoms facilitate further functionalization.
• Ligand & Catalyst Preparation: Employed in the preparation of sophisticated ligands for transition metal catalysis, enabling challenging cross-coupling reactions.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the production of high-temperature resins, polyimides, and flame-retardant materials.
• Organic Electronic Materials: Investigated as a core structure for hole-transport materials (HTMs) or electron-accepting units in organic light-emitting diodes (OLEDs) and photovoltaics.
• Research & Development: A valuable tool for academic and industrial research in exploring new reaction pathways and creating novel chemical entities.

Quality Control

Our 1,4-Benzenediamine, N1,N1,N4,N4-Tetrakis(4-Bromophenyl)- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and NMR for structural confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing batch-specific results are provided and 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 flames.
