Quality Control

Every batch of 4-Penten-2-One, 3-Ethyl-3-Methyl- (9Ci) is produced and tested under strict quality management protocols to ensure consistency and purity for sensitive synthetic applications. Our products undergo rigorous quality testing, including chromatographic analysis, to ensure compliance with industry standards and customer specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, we recommend storing under an inert gas such as nitrogen or argon and keeping the container tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
