Quality Control

Our 2,5,5-Tris(trimethylsilyl)-1,3-cyclopentadiene, 99 is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR, GC, and HPLC, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee it meets your research and production 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.
