Quality Control

Our production of 4,5,5,6,6,6-Hexafluoro-4-(Trifluoromethyl)-2-Hexenoic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

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-lined). Recommended long-term storage temperature is 2-8°C.
