Quality Control

Our 1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-Pentadecafluoroheptane-1-Sulphonic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications and test results is provided with each shipment to guarantee 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 strong acid properties, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C.
