Quality Control

Our Dichloroaluminum is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and reliability. Quality is verified through a comprehensive suite of analytical techniques including titration, IR spectroscopy, and impurity profiling. Certificates of Analysis (COA) detailing purity, assay, and specific impurity limits are provided with each shipment. We adhere to relevant industry standards and can support compliance requirements for REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere such as argon or nitrogen in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C to maximize stability. Keep away from strong acids and organic solvents.
