Quality Control

Every batch of 5H-Octafluoropentanoyl Chloride is manufactured and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including GC, NMR, and FTIR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 2-8°C (refrigerated) or as specified upon receipt. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent hydrolysis.
