Quality Control

Our L-Tyrosine, 3-Methoxy-o-Methyl-, Ethyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the exacting standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and specification compliance.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
