Quality Control

Our 3-Penten-2-One, 3-Ethyl-, (Z)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by GC or HPLC, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and isomer content is provided with every shipment to guarantee batch-to-batch consistency and traceability for our customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its properties as a highly volatile and easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong acids, bases, and oxidizing agents.
