Quality Control

Our 3,3,4,4,5,5,6,6,7,7,7-Undecafluoroheptane-1-Sulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, it should be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain purity and prevent hydrolysis. Recommended storage temperature is 2-8°C.
