Quality Control

Our production of Phosphinous Chloride, Bis(2,2-Dimethylpropyl)- adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay (by GC or NMR), identity confirmation (IR), and impurity profiling, to ensure consistency and high purity suitable for synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your specifications.

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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent decomposition. Keep away from strong oxidizers, bases, and moisture.
