Quality Control

Our Magnesium Diphenyl is manufactured under stringent quality protocols to ensure batch-to-batch consistency and high reactivity. Quality is assured through comprehensive analytical testing, including titration for assay determination and spectroscopic methods for identity confirmation. A Certificate of Analysis (COA) detailing purity, concentration (typically supplied as a solution in specific solvents like THF or diethyl ether), and impurity profiles is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive and moisture-sensitive nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for solutions to maintain stability. Isolate from oxidizing agents, acids, and moisture.
