Quality Control

Our (S)-2-Aminoundecanoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing identity, purity (typically ≥98%), enantiomeric excess, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
