Description

Trichlorotrimethyl Dialuminum is an organoaluminum compound with the CAS number 12542-85-7, serving as a versatile precursor and catalyst in advanced material synthesis. Its value lies in its ability to act as a highly reactive source of aluminum and methyl groups under controlled conditions, enabling precise chemical transformations. This compound is essential for researchers and manufacturers in the semiconductor, polymer, and fine chemical industries who require specialized organometallic reagents for deposition, alkylation, and catalysis processes.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): A key precursor for depositing high-purity aluminum-containing thin films, such as aluminum nitride (AlN) or aluminum oxide (Al2O3), in semiconductor and optical device manufacturing.
• Polymerization Catalyst: Functions as a co-catalyst or activator in Ziegler-Natta and other olefin polymerization systems for producing polyolefins.
• Organic Synthesis: Used as a methylating or aluminum-transfer agent in the synthesis of complex organic molecules and pharmaceuticals.
• Material Science Research: Employed in the development of novel metal-organic frameworks (MOFs), ceramics, and composite materials.
• Specialty Chemical Manufacturing: Serves as an intermediate in the production of other organoaluminum compounds and aluminum-based reagents.

Quality Control

Our Trichlorotrimethyl Dialuminum is produced and handled under stringent quality management protocols 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 specific results is provided with every shipment. We adhere to relevant industry standards and can support requirements for research, development, and industrial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Keep away from heat, open flames, and incompatible materials such as strong acids, organic solvents, and oxidizing agents. Recommended long-term storage temperature is 2-8°C.
