Quality Control

Our [Phthaloylbis(Oxy)]Bis[Dibutyl(Octyloxy)Stannane] is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and meets defined specifications for catalytic activity and purity. A comprehensive Certificate of Analysis (COA) detailing assay, tin content, and impurity profiles is provided with every shipment to guarantee traceability and performance for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and hydrolysis. Keep away from strong acids and strong bases.
