Description

Aluminum(+3) Cation: 2-Methylpropane is a specialized organoaluminum compound where the aluminum cation is coordinated with an isobutane-derived ligand. This compound matters for its role as a highly reactive Lewis acid catalyst and precursor in advanced material synthesis. Industries requiring precise polymerization control, such as specialty polymer and fine chemical manufacturing, need this high-purity reagent for its consistent performance and predictable reactivity profile.

Application

• As a cocatalyst or activator in Ziegler-Natta and metallocene polymerization systems for polyolefins.
• As a Lewis acid catalyst in Friedel-Crafts alkylation and acylation reactions within fine chemical synthesis.
• As a precursor material in the chemical vapor deposition (CVD) or atomic layer deposition (ALD) of aluminum-containing thin films.
• In the synthesis of organoaluminum reagents used as reducing agents or alkylating agents in organic chemistry.
• For research and development in novel catalytic systems and material science applications.

Quality Control

Our Aluminum(+3) Cation: 2-Methylpropane is manufactured under stringent quality systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing specifications and test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and pyrophoric nature, this material must be stored under an inert atmosphere (nitrogen or argon) in a cool, dry, well-ventilated area, away from heat, ignition sources, and oxidizing agents. Recommended storage temperature is 2-8°C for extended stability.
