Quality Control

Our 1,4-Bis(Trimethylsilyl)-1,3-Butadiyne is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment upon request.

Storage

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