Quality Control

Our 3,4-Dichloro-Dl-Phenylalanine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, chiral analysis, and residual solvent screening, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and potential degradation.
