Quality Control

Our 3,5-Bis(Trimethylsilyl)-3,4-Heptadiene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR analysis, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality system is designed to meet the stringent requirements of research and fine chemical synthesis applications.

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 must 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. Keep away from heat, sparks, and open flame.
