Quality Control

Our production of Phosphonous Dichloride, (2-Chloro-1,1-Dimethylethyl)- adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Each lot undergoes comprehensive analysis including GC, NMR, and titration methods to verify identity, assay, and impurity profiles. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled 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) after opening to prevent decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
