Description

Di-n-Butylaluminum Chloride is an organoaluminum compound widely used as a versatile catalyst and reagent in organic synthesis. This compound is valued for its strong Lewis acidity and its ability to facilitate key transformations in polymerization and fine chemical manufacturing. It is essential for industries involved in producing specialty polymers, pharmaceuticals, and advanced materials, where precise catalytic control is required.

Application

• As a co-catalyst in Ziegler-Natta type systems for the polymerization of olefins such as ethylene and propylene.
• As a Lewis acid catalyst in Friedel-Crafts alkylation and acylation reactions for fine chemical synthesis.
• As an activator and chain transfer agent in the production of polyalphaolefins (PAO) and other synthetic lubricants.
• As a key reagent in the synthesis of organometallic complexes and other aluminum-containing compounds.
• In the pharmaceutical industry for mediating stereoselective reactions in active pharmaceutical ingredient (API) development.
• For the production of linear alkylbenzenes (LAB), which are precursors to biodegradable surfactants.

Quality Control

Our Di-n-Butylaluminum Chloride is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. The product is analyzed using advanced techniques including titration and gas chromatography to verify key parameters such as active aluminum content and chloride concentration. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this material must be stored under a dry, inert atmosphere (argon or nitrogen) in a cool, well-ventilated area, away from heat and ignition sources. Recommended storage temperature is 2-8°C for long-term stability. Keep away from moisture, strong acids, and strong oxidizing agents.
