Quality Control

Our production of Dimethyl 11-Butyl-11-[[2-[(6-Methoxy-1,6-Dioxohexyl)Oxy]Ethyl]Thio]-6,16-Dioxo-7,15-Dioxa-10,12-Dithia-11-Stannahenicosanedioate adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and ICP-MS for heavy metal content, to ensure it meets precise customer specifications. Certificates of Analysis (COA) detailing all test results are provided with each shipment to guarantee traceability, consistency, and compliance with relevant industry standards.

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). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
