Quality Control

Our (H-Cys-Pna)2 is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment, identity confirmation by IR and NMR spectroscopy, and tests for residual solvents and moisture content. 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 a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and performance. For long-term storage, consider desiccants or inert atmosphere.
