Description

Aluminium Tri-sec-Butoxide is a versatile organoaluminium compound widely used as a catalyst and chemical intermediate. Its value lies in its ability to facilitate key organic transformations and serve as a precursor for advanced materials. This product is essential for manufacturers and R&D facilities in the pharmaceutical, fine chemical, and specialty polymer industries seeking reliable, high-purity reagents.

Application

• Catalyst in Organic Synthesis: Employed as a Lewis acid catalyst in various reactions, including esterifications, transesterifications, and the Meerwein-Ponndorf-Verley reduction.
• Precursor for Alumina Coatings: Used in sol-gel processes to deposit thin films of aluminum oxide (alumina) for optical, electronic, and protective coating applications.
• Chemical Intermediate: Serves as a key starting material for the synthesis of other organoaluminium compounds and metal-organic frameworks (MOFs).
• Polymerization Catalyst/Co-catalyst: Utilized in the production of polyesters and other polymers where precise control over molecular weight and structure is required.
• Pharmaceutical Intermediate: Used in the synthesis of certain active pharmaceutical ingredients (APIs) and complex organic molecules.
• Crosslinking Agent: Functions as a crosslinker in silicone resins and other polymer systems to enhance thermal and mechanical properties.

Quality Control

Our Aluminium Tri-sec-Butoxide is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) are provided with every shipment and are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
