Quality Control

Every batch of 5-(4-Chloro-1,1,2,2,3,3,4,4-Octafluorobutylsulfonyl)-2-Ethoxy-6-Phenyl-4-p-Tolyl-3,4-Dihydro-2H-Pyran undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of research and development, as well as pre-clinical manufacturing. A comprehensive Certificate of Analysis (COA) detailing purity (typically ≥95% by HPLC), identity confirmation, and impurity profile is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is sensitive to fluoride/strong alkali. Keep away from incompatible materials such as strong bases and reactive metals. For long-term storage, consider inert gas purging to maintain stability.
