Quality Control

Our Dl-β-(3-Bromophenyl)Alanine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis to confirm the racemic mixture, and identity confirmation via IR and NMR spectroscopy. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with research and development grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
