Quality Control

Our 1,1,3,3-Tetrachloro-1,3-Disilabutane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR, to ensure high purity and consistency suitable for demanding applications like semiconductor processing. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
