Quality Control

Our 2-(2-Chloroethoxy)-1,3,2-Dioxaphospholane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopic methods (NMR, IR), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every 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 place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation by moisture.
