Quality Control

Our Phenethyldimethylchlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration, 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, well-ventilated area at 2-8°C under an inert atmosphere (argon or nitrogen). Due to its highly volatile and hygroscopic nature, the container must be kept sealed and handled under dry conditions to prevent hydrolysis and moisture ingress.
