Quality Control

Our Boc-4-Bromo-Dl-Phenylalanine Methyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

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 tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and handling properties.
