Quality Control

Our 4-Tributylstannyl-5H-Furan-2-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹³C, ¹¹⁹Sn), HPLC, and Karl Fischer titration, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry, and well-ventilated place. Due to its moisture-sensitive and easily oxidized nature, the container should be allowed to reach room temperature before opening to prevent condensation.
