Quality Control

Our Chloro(Pentyloxy)Magnesium is manufactured under stringent process controls to ensure batch-to-batch consistency and high reactivity. Quality is verified through analytical methods including titration and gas chromatography (GC) to confirm concentration and purity in standard solution formats. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and solution concentration is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile, hygroscopic (moisture-sensitive), and easily oxidized 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 extended stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and oxidizers.
