Quality Control

Our H-Leu-Trp-Leu-Oh is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation via mass spectrometry and NMR. Certificates of Analysis (COA) with detailed chromatographic data are provided to ensure the material meets your specific research or development grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 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.
