Quality Control

Our Methyl (9Z,11E)-13-Oxooctadeca-9,11-Dienoate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and isomer ratio confirmation, GC for residual solvent analysis, and spectroscopic methods (IR, NMR) for structural verification. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or manufacturing specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. For long-term storage, consider inert gas (argon/nitrogen) purging to minimize oxidation.
