Quality Control

Our [(1E)-1,2-Difluoro-1,2-Ethenediyl]Bistributylstannane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical characterization, including NMR (¹H, ¹³C, ¹⁹F), GC-MS, and elemental analysis (Tin, Fluorine). A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment, supporting your R&D and scale-up activities with reliable data.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from heat, sparks, and open flame. Due to its sensitivity to oxidation and moisture, containers should be sealed immediately after use.
