Quality Control

Our Octadecafluoro-9-(Trifluoromethyl)Decanoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration or HPLC, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and specific impurity profiles are provided with every shipment to support your quality assurance protocols.

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, fluoropolymer-lined). Recommended storage temperature: 15-25°C.
