Quality Control

Our Msh, 2-(3,5-Diiodo-Tyr)α- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via mass spectrometry, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment. For long-term storage, consider under inert atmosphere.
