Quality Control

Our 2-Methyl-7-(Tributylstannyl)-2,4,6-Heptatrienoic Acid Ethyl Ester is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR and HPLC analysis, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee it meets the stringent requirements of research and process chemistry applications.

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.
