Quality Control

Our 5,5-Dibutyl-3,3,7,7-Tetramethoxy-2,4,6,8-Tetraoxa-3,7-Disila-5-Stannanonane is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including NMR, FT-IR, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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) after opening to prevent degradation. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
