Quality Control

Our production of 3-(Ethoxydimethylsilyl)Propiononitrile adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific customer or regulatory requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
