Quality Control

Our Methyl 2,2,3,3,4,4-Hexafluoro-4-[(1,2,2-Trifluoroethenyl)Oxy]Butanoate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including GC, NMR, and FTIR to confirm identity and purity. We provide detailed Certificates of Analysis (COA) with every shipment, ensuring traceability and compliance with your internal specifications and Good Manufacturing Practice (GMP) guidelines for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed at temperatures between 2°C and 25°C. Handle and store under an inert atmosphere (e.g., nitrogen) for long-term stability.
