Quality Control

Our L-Ornithine, 2-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the stringent requirements for research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, enantiomeric excess, and related substances.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
