Quality Control

Our H-Val-Tyr-Ser-βna is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure high purity and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes data from HPLC, NMR, and MS analysis. Our quality commitment aligns with standards expected for pharmaceutical intermediates and research-grade biochemicals.

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 sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
