Quality Control

Every batch of 2,5-Bis(Tri-n-Butylstannyl)Furan undergoes rigorous analytical testing to ensure high purity and consistency suitable for sensitive cross-coupling applications. Our standard quality protocol includes NMR (1H, 13C, 119Sn) for structural confirmation, HPLC/GC for purity assessment, and elemental analysis (Tin content). A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry place at 2-8°C to minimize oxidation and hydrolysis. This material is moisture-sensitive (hygroscopic) and easily oxidized; ensure containers are sealed immediately after use. Keep away from strong acids and oxidizing agents.
