Quality Control

Our Mpeg11-Ch2Ch2Cooh is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 2-8°C or as indicated on the label. Due to its hygroscopic nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
