Quality Control

Our Tetradecyl 5,5-Dioctyl-9-Oxo-10-Oxa-4,6-Dithia-5-Stannatetracosanoate is manufactured under strict quality protocols. Each batch undergoes rigorous testing to ensure compliance with industry specifications for organotin intermediates and stabilizers. A comprehensive Certificate of Analysis (COA) detailing assay, tin content, and impurity profiles is provided with every shipment to guarantee consistent quality and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. This compound is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to maintain purity and prevent degradation. Keep away from strong acids and strong oxidizing agents.
