Quality Control

Our Tributyl[(p-tert-Butylbenzoyl)Oxy]Stannane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for synthetic applications. We adhere to current Good Manufacturing Practices (cGMP) where applicable. Comprehensive testing, including assay and impurity profile analysis, is performed. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its organotin nature and light-sensitive properties, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
