Quality Control

Every batch of Diethyl(Ethyldimethylsilanolato)Aluminium is manufactured and tested under stringent quality management protocols to ensure high purity, consistency, and reliability for industrial and research applications. Our products undergo rigorous quality testing, including NMR and titration assays, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive and moisture-sensitive nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and incompatible materials such as oxidizers, acids, and water.
