Quality Control

Our H-Tyr-Ala-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for enantiomeric excess, and identity confirmation via IR and NMR spectroscopy. We provide Certificates of Analysis (COA) with detailed specifications for trace metals, residual solvents, and related substances, ensuring compliance with research and cGMP-grade standards for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere.
