Quality Control

Our S-(2-Aminoethyl)-L-Cysteine Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification (IR, NMR), purity assay (HPLC), and specific tests for impurities and optical rotation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture absorption. For long-term storage, consider storing under an inert atmosphere.
