Quality Control

Every batch of our 2-(2-Chloroethoxy)-5-(Hydroxymethyl)-5-[[[Bis(2-Chloroethoxy)Phosphinyl]Oxy]Methyl]-1,3,2-Dioxaphosphorinane 2-Oxide is manufactured under strict quality management protocols. We employ advanced analytical techniques including HPLC, NMR (¹H, ³¹P), and GC-MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment, and we support custom purity requirements for specific applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
