Quality Control

Our o-Phospho-Dl-Tyrosine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and specific tests for residual solvents and moisture. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification results. Our quality commitment ensures the product meets the high standards required for research and pharmaceutical applications.

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 desiccants or inert atmosphere.
