How should Aluminium trifluoride (CAS: 7784-18-1) be stored?

Aluminium trifluoride (CAS: 7784-18-1) should be stored in airtight, moisture-proof containers in a cool, dry place away from light. It is hygroscopic and reacts with water, so desiccant drying is essential. Storage must avoid exposure to humidity and ensure proper ventilation to prevent vapor accumulation. Maintain stability by keeping it sealed and in a controlled environment.
