Quality Control

Our Tetraethyldialuminoxane is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. Production adheres to relevant ISO 9001 standards, and all materials are handled in controlled environments to prevent contamination. 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 highly volatile and easily oxidized nature, this material must be stored and handled under an inert atmosphere (argon or nitrogen). Recommended storage temperature is 2-8°C to minimize decomposition and maintain stability. Keep away from moisture, heat, and incompatible materials such as strong acids, oxidizers, and halogens.
