Quality Control

Our 2-Ethylhexyl [(Tributylstannyl)Thio]Acetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for industrial applications. Certificates of Analysis (COA) documenting purity, tin content, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) after opening. Keep away from strong alkalis and incompatible materials. Observe all local regulations for storing organometallic compounds.
