Quality Control

Our 2,5-Diaminoadipic Acid 2Hcl is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and residual solvent screening, to ensure it meets the high standards required for research and pharmaceutical applications. Certificates of Analysis (COA) with full traceability are provided with every shipment.

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 use to prevent moisture absorption, which can affect stability and handling properties.
