Quality Control

Our H-Arg-Ala-Oh Acoh is manufactured under strict quality systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting specifications for assay, chiral purity, and residual solvents. Production can be aligned with cGMP guidelines for advanced pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label or COA. This material is hygroscopic (moisture-sensitive) and should be handled under dry conditions to maintain stability. For long-term storage, consider desiccation.
