Quality Control

Our L-Asn-L-Cys-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and residual solvent screening, to ensure it meets stringent specifications for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. The product is hygroscopic and should be kept in a cool, dry place. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
