Quality Control

Every batch of our 1,3-Dichloro-1,3-Dimethyldialuminoxane solution is manufactured and tested under stringent quality management systems. We ensure consistent molarity, purity, and performance as a critical reagent. A comprehensive Certificate of Analysis (COA) detailing assay, solvent content, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at room temperature (15-25°C) in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its properties of being easily oxidized and highly volatile, the container must be kept sealed and handled using appropriate inert techniques to prevent exposure to moisture and air.
