Quality Control

Our H-Arg-Trp-Oh Hydrochloride Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and specific tests for residual solvents and heavy metals. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. Due to its hygroscopic nature, the container should be kept in a desiccated environment and allowed to equilibrate to room temperature before opening to minimize moisture uptake.
