Quality Control

Our Silane, (1-Ethynylcyclopropyl)Trimethyl- (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your R&D and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for long-term stability.
