Quality Control

Our Cyclosiloxanes, Me 3-(Oxiranylmethoxy)Propyl is manufactured under a strict quality management system to ensure high purity and consistent reactivity. Each production batch undergoes rigorous analytical testing, including assay by GC or HPLC and epoxy value determination. A comprehensive Certificate of Analysis (COA) documenting identity, purity, and key specifications 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 area at room temperature (15-25°C). The product is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain epoxy functionality. Keep away from strong acids, bases, and oxidizing agents.
