Quality Control

Our 2-Ethylhexyl 4-[[Dibutyl(Dodecylthio)Stannyl]Oxy]-4-Oxoisocrotonate 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 use. 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 room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque packaging or dark storage conditions.
