Quality Control

Our Bis(Tri-n-Butyltin) Itaconate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay and impurity profiling, to ensure it meets precise specifications and industry requirements. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and consistency for your production needs.

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 easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
