Description

4-Methoxy-N,n-Bis[4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]Benzenamine is a high-purity, advanced organic building block featuring multiple boronic ester functional groups. This compound is critical for enabling complex cross-coupling reactions, particularly in the synthesis of sophisticated organic electronic materials and pharmaceuticals. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries who require precise molecular architecture for their synthetic pathways.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: Serves as a key monomer or intermediate in the synthesis of complex conjugated polymers and small molecules for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs).
• Pharmaceutical Intermediate: Used in the research and development of active pharmaceutical ingredients (APIs), especially those requiring specific aryl-aryl linkages.
• Agrochemical Synthesis: Employed as a building block for creating novel herbicides, fungicides, and insecticides with tailored properties.
• Material Science Research: Facilitates the creation of novel organic frameworks (MOFs, COFs) and advanced functional materials with specific electronic or optical characteristics.
• Liquid Crystal and Dye Manufacturing: Acts as a precursor for synthesizing specialized dyes and liquid crystal compounds for display technologies.
• Polymer Modification: Enables the functionalization of polymer chains to introduce boronic ester handles for further chemical modification or sensing applications.

Quality Control

Our 4-Methoxy-N,n-Bis[4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]Benzenamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR (1H and 13C), and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can support development projects requiring compliance with ICH guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon or nitrogen) when possible to maintain stability and prevent hydrolysis of the boronic ester groups. Keep away from heat and incompatible materials.
