Quality Control

Our Tributylstannyl Methanesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and identification by spectroscopic methods, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to strong alkali and organic solvents, keep away from incompatible materials. Containers must be kept tightly sealed to prevent moisture absorption and oxidation.
