Quality Control

Our (4,8-Bis((2-Hexyldecyl)Oxy)Benzo[1,2-B:4,5-B']Dithiophene-2,6-Diyl)Bis(Trimethylstannane) is manufactured under strict inert atmosphere conditions to prevent oxidation and hydrolysis. Each batch undergoes rigorous analytical testing, including NMR (1H, 13C) and HPLC analysis, to ensure high chemical purity and consistent performance as a polymerization monomer. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C or as specified on the label. This compound is moisture-sensitive and easily oxidized; prolonged exposure to air, light, or ambient humidity must be avoided to maintain reactivity and purity. Keep the container sealed and desiccated when not in use.
