Quality Control

Our 2,2,3,3,4,4,5,5-Octafluoro-1,6-Hexanediol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and compliance with customer specifications. Standard testing includes assay (HPLC), identity confirmation (IR, NMR), and impurity profiling. Comprehensive Certificates of Analysis (COA) documenting all test results are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To prevent degradation and clumping, the container must be kept tightly sealed when not in use and consideration should be given to storage under an inert atmosphere for long-term preservation.
