Description

Aluminium-Dimethylbromid CAS NO 3017-85-4 is a highly reactive organoaluminium compound primarily used as a versatile alkylating agent and catalyst precursor in advanced organic synthesis. Its value lies in its ability to facilitate key transformations, such as carbon-carbon bond formation and polymerization initiation, with high efficiency and selectivity. This chemical is essential for R&D laboratories and industrial-scale production in the pharmaceutical, agrochemical, and specialty polymer sectors, where precise and controlled alkylation is required.

Application

• As a potent alkylating agent in the synthesis of complex organic molecules and active pharmaceutical ingredients (APIs).
• As a cocatalyst or precursor in Ziegler-Natta and other olefin polymerization systems for producing polyolefins.
• In fine chemical synthesis for the introduction of methyl groups under mild conditions.
• As a reducing agent in specific organic transformations and metalorganic chemistry.
• In material science research for the deposition of aluminium-containing thin films via chemical vapor deposition (CVD) or atomic layer deposition (ALD) techniques.
• For the preparation of other organometallic reagents and catalysts through transmetalation reactions.

Quality Control

Our Aluminium-Dimethylbromid is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable, and the material is characterized using advanced analytical techniques including NMR, GC, and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly hygroscopic and pyrophoric nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area, away from moisture, heat, and incompatible materials such as strong oxidizers, acids, and alcohols. For long-term stability, storage at 2-8°C is recommended. Handle only in a certified fume hood or glovebox.
