Quality Control

Our (E)-Cyano(3-Phenoxyphenyl)Methyl 2,2-Dimethyl-3-(3,3,3-Trifluoroprop-1-En-1-Yl)Cyclopropanecarboxylate is manufactured under strict quality management systems. The product undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent isomeric ratio, which is critical for downstream synthesis efficiency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every batch to ensure compliance with your technical specifications.

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). This material is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain stability and purity. Keep away from heat, sparks, and open flame.
