Quality Control

Our 5,9-Dibutyl-5,9-Dichloro-7-Hydroxy-6,8-Dioxa-7-Phospha-5,9-Distannatridecane 7-Oxide is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and elemental analysis, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all critical specifications. Our quality system is designed to meet the stringent requirements of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C. Keep away from strong acids, strong bases, and oxidizing agents. Due to the presence of organotin and hydrolyzable chloride groups, the material should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
