Description

Methylaluminum Bis(2,6-Di-tert-Butyl-4-Methylphenoxide) is a sterically hindered organoaluminum compound, specifically a methylaluminum bisphenoxide, valued for its unique Lewis acidity and selectivity as a catalyst or co-catalyst. This compound matters for enabling precise polymerization and organic synthesis reactions where controlled reactivity and reduced sensitivity to impurities are critical. It is primarily needed by researchers and manufacturers in the polymer industry, particularly for the development of advanced polyolefins and specialty chemicals.

Application

• As a catalyst or co-catalyst component in Ziegler-Natta type olefin polymerization systems.
• As a Lewis acid catalyst in selective organic transformations, such as Friedel-Crafts alkylation or acylation.
• For the synthesis of tailored polyolefins with specific microstructures and properties.
• In academic and industrial R&D for exploring new catalytic pathways and material science.
• As a precursor or modifying agent for other organometallic complexes.
• Potential use in fine chemical synthesis where a hindered, moisture-sensitive Lewis acid is required.

Quality Control

Our Methylaluminum Bis(2,6-Di-tert-Butyl-4-Methylphenoxide) is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for catalytic applications. All products undergo rigorous quality testing, including assay and impurity profiling. Certificates of Analysis (COA) detailing specific lot results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under a dry, inert atmosphere (argon or nitrogen) at controlled room temperature (15-25°C) in a cool, dry, well-ventilated place. This material is both hygroscopic (moisture-sensitive) and easily oxidized; exposure to air or moisture must be minimized to maintain purity and reactivity.
