Quality Control

Our H-Ala-Arg-OH is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for enantiomeric purity, and identity confirmation by IR and MS. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under dry, inert conditions to maintain stability and purity. For long-term storage, consider desiccated environments.
