Quality Control

Our Divinyldi-n-Butyltin is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting requirements of industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

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) after opening to prevent degradation. Keep away from incompatible materials such as strong acids and oxidizing agents.
