Quality Control

Our production of (5-Ethyl-2-Methyl-1,3,2-Dioxaphosphorinan-5-Yl)Methyl Dimethyl Phosphonate p-Oxide adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure consistency and meet exacting customer specifications. A Certificate of Analysis (COA) detailing all relevant parameters is provided with every shipment to guarantee traceability and compliance with your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat sources and incompatible materials.
