Quality Control

Our 4 4 4-Trifluoro-3-Methyl-2-Butenoic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
