Quality Control

Our Asp-His-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by IR and NMR spectroscopy. We provide Certificates of Analysis (COA) with detailed results for all critical parameters, ensuring traceability and compliance with your research or cGMP-grade requirements.

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 sealed in a desiccated environment to prevent product degradation and ensure long-term stability.
