Quality Control

Our H-Thr-Lys-Pro-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and chiral purity analysis. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, detailing all critical quality attributes to ensure compliance with your research or cGMP guidelines.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
