Quality Control

Our Bis(Dichlorophosphino)Methane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through advanced analytical techniques including NMR, GC, and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
