Quality Control

Our 1,4-Bis(Trimethylstannyl)-2,3,5,6-Tetrachlorobenzene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including NMR (¹H, ¹³C, ¹¹⁹Sn), HPLC, and elemental analysis (Tin, Chlorine), to verify identity and assay. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment, ensuring full traceability and compliance with research and industrial application requirements.

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 the organotin content and light-sensitive nature, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain stability and prevent decomposition. Keep away from heat, sparks, and open flame.
