Quality Control

Our n-Me-Tyr-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability, consistency, and compliance with your 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
