Quality Control

Our 5H-Octafluoropentanoic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, GC, and HPLC analysis, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical parameters. Our quality commitment ensures the material meets the stringent requirements for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent, containers must be kept tightly sealed and constructed of compatible materials (e.g., PTFE, fluorinated polymers). Recommended storage temperature is 2-8°C for long-term stability.
