Quality Control

Our [2,3,5,6-Tetrafluoro-4-(Methoxymethyl)Phenyl]Methyl 2,2-Dimethyl-3-Pro p-1-Enyl-Cyclopropane-1-Carboxylate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency suitable for industrial synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store this material under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
