Quality Control

Our (2E,4E)-Nona-2,4-Dienoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and stereochemical confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

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). This material is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, consider packaging under an inert gas such as nitrogen or argon.
