Quality Control

Our (2,3-Quinoxalinyldithio)Dimethyltin is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration or HPLC, identification by FT-IR, and quantification of key impurities. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents and acids.
