Quality Control

Our Bis(Tri-n-Butyltin) Sulfate is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and identification by FT-IR, to ensure it meets precise specifications for purity and consistency. Certificates of Analysis (COA) detailing all quality parameters are available upon request to support your regulatory and quality assurance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. Keep away from strong acids and incompatible organic solvents.
