Quality Control

Our Methyl Lysinate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, detailing key parameters such as assay, enantiomeric purity, and impurity profiles. Our quality commitment supports applications requiring high-purity building blocks for sensitive synthetic processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
