Quality Control

Our 4-Oxo-9,11,13-Octadecatrienoic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere if specified. Keep away from strong oxidizing agents.
