Quality Control

Our 1,2-Bis(Trimethylstannyl)-3,4,5,6-Tetrachlorobenzene is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for research and development applications. All products undergo rigorous analytical testing, including NMR (1H, 13C, 119Sn), HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C to minimize oxidation and hydrolysis. This material is moisture-sensitive (hygroscopic) and should be handled in a dry, controlled environment. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
