Quality Control

Our n-(1-Oxooctadecyl)-DL-Methionine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, IR, and titration methods, to ensure it meets precise specifications for identity, purity, and consistency. Certificates of Analysis (COA) documenting all test results 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, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
