Description

9-(3,5-Dimethylphenyl)-2,7-Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-9H-Carbazole is a high-purity, functionalized carbazole derivative featuring pinacol boronate ester groups at the 2 and 7 positions, making it a critical advanced organic intermediate for cross-coupling reactions. This compound is essential for researchers and manufacturers developing next-generation organic electronic materials, including OLEDs, OFETs, and perovskite solar cells. It is primarily sought by R&D laboratories and production facilities in the pharmaceutical, agrochemical, and specialty materials sectors for constructing complex conjugated molecular architectures.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: Serves as a key monomer for constructing conjugated polymers and small molecules used in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs).
• Pharmaceutical Intermediate: Used in the synthesis of complex drug candidates, particularly those containing carbazole cores with specific substitution patterns for targeted biological activity.
• Agrochemical Synthesis: Employed in creating novel active ingredients with enhanced efficacy and environmental profiles.
• Material Science Research: A fundamental building block for developing novel organic semiconductors, hole-transport materials, and luminescent materials.
• Perovskite Solar Cell Components: Utilized in the synthesis of hole-transporting materials (HTMs) and interfacial layers to improve device efficiency and stability.
• Liquid Crystal and Dye Manufacturing: Acts as a precursor for functional dyes and liquid crystal compounds requiring precise molecular alignment and electronic properties.

Quality Control

Every batch of 9-(3,5-Dimethylphenyl)-2,7-Bis(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-9H-Carbazole is manufactured under strict quality management protocols. We employ advanced analytical techniques including HPLC, NMR (1H and 13C), and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory requirements.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent degradation. Keep away from heat and incompatible materials.
