Quality Control

Our production of (E)-[(3,7-Dimethyl-2,6-Octadienyl)Oxy]Dimethoxymethylsilane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and isomer confirmation, NMR for structural verification, and Karl Fischer titration for moisture content, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided to guarantee traceability, consistency, and compliance with your R&D or manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored under an inert atmosphere (nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C to maximize shelf-life stability. Allow the container to reach room temperature before opening to prevent moisture condensation.
