Quality Control

Our 1,1,3-Tris[(1,1-Dimethylethyl)Dimethylsilyl]-1,2-Butadiene is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (¹H and ¹³C), GC or HPLC for purity assessment, and FT-IR for structural confirmation, to ensure compliance with stringent specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical R&D and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C (refrigerated) or as indicated on the specific product label.
