Quality Control

Our H-Gly-Phe-Tyr-Oh is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for stereochemical integrity, and identity confirmation via mass spectrometry. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure full traceability and compliance with your research or cGMP guidelines 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). 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.
