Quality Control

Our Cyclotrimethylenedimethylsilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) and nuclear magnetic resonance (NMR) spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and product loss.
