Description

Bis(Trimethylaluminum)-1,4-Diazabicyclo[2.2.2]Octane Adduct is a highly specialized organoaluminum compound, specifically an adduct of trimethylaluminum (TMA) with the Lewis base DABCO (1,4-diazabicyclo[2.2.2]octane). This formulation is engineered to provide a more stable, safer-to-handle, and precisely controllable source of aluminum and methyl groups compared to its pyrophoric parent compound. It is a critical precursor and co-catalyst in advanced materials synthesis and fine chemical manufacturing. Industries requiring high-purity, reproducible organometallic reagents for catalysis and thin-film deposition are the primary users of this material.

Application

• Metal-Organic Chemical Vapor Deposition (MOCVD): A key aluminum source for the epitaxial growth of high-performance semiconductor films, such as aluminum nitride (AlN) and aluminum gallium nitride (AlGaN), used in LEDs and power electronics.
• Advanced Polymerization Catalysis: Serves as a co-catalyst or activator in Ziegler-Natta and metallocene catalyst systems for the production of polyolefins and other specialty polymers.
• Fine Chemical Synthesis: Utilized as a methylating or aluminum-transfer agent in the synthesis of complex pharmaceutical intermediates and organic molecules under controlled conditions.
• Material Science Research: Employed in the development of novel metal-organic frameworks (MOFs), ceramic precursors, and other advanced inorganic-organic hybrid materials.
• Atomic Layer Deposition (ALD): Acts as a precursor for depositing ultra-thin, conformal aluminum oxide (Al2O3) films for microelectronics and surface passivation.

Quality Control

Our Bis(Trimethylaluminum)-1,4-Diazabicyclo[2.2.2]Octane Adduct is manufactured under stringent controls to ensure batch-to-batch consistency and high purity, critical for sensitive applications like MOCVD and catalysis. All products undergo rigorous quality testing, including assay and impurity profiling, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing specific lot results are available upon request. We support customer audits and can provide material to meet the exacting requirements of advanced materials manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Due to its moisture-sensitive and potentially pyrophoric nature upon decomposition, the container must be kept sealed and handled using appropriate air-free techniques. Recommended long-term storage temperature is 2-8°C.
