Quality Control

Our Bis(Hydrogen Diphenylmethylphosphonato)Magnesium is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Minimize exposure to air and moisture during handling to maintain product integrity.
