Quality Control

Our Erythro-Dl-β-Methylphenylalanine Hydrochloride is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the specified 99% minimum purity standard. A comprehensive Certificate of Analysis (COA) detailing identity, purity, residual solvents, and related substances is provided with every shipment to guarantee traceability and compliance with your research or cGMP starting material requirements.

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 must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
