Quality Control

Our Ethylaluminum Dichloride is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including titration, gas chromatography (GC), and NMR spectroscopy. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this material must be stored under a dry, inert atmosphere (argon or nitrogen) in a cool, well-ventilated area, away from heat and ignition sources. Keep container tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
