Quality Control

Our Tri-n-Butylaluminum is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity for demanding industrial applications. Quality is verified through analytical methods including titration and gas chromatography. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment to guarantee compliance with your technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (nitrogen or argon) in a cool, dry, well-ventilated area, away from heat, ignition sources, and incompatible materials such as water, alcohols, and oxidizing agents. Due to its pyrophoric nature, it must be handled and stored exclusively under an inert gas. Recommended storage temperature is 2-8°C for extended stability.
