Storage Store in a cool, dry place away from moisture and incompatible substances

Aluminum(III) Chloride should be stored in a cool, dry environment to prevent moisture absorption, which can lead to decomposition. It is recommended to keep it in airtight containers made of materials such as glass or polyethylene to avoid chemical interactions. Due to its reactivity, it should be handled in a well-ventilated area, and appropriate personal protective equipment should be worn. Avoid contact with water or moisture, as it can cause exothermic reactions. Regular inspection of storage conditions ensures the material remains stable and safe for use in laboratory settings.
