Quality Control

Our (E)-5,5,12,12-Tetrabutyl-7,10-Dioxo-6,11-Dioxa-5,12-Distannahexadec-8-Ene is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and batch-to-batch consistency. Comprehensive Certificates of Analysis (COA) detailing identity, purity, 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 at a controlled room temperature (15-25°C). 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. Keep away from heat and incompatible materials.
