Quality Control

Our 3-Isobutyl-2,2-Dimethylcyclopropanecarboxylic Acid Ethyl Ester is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
