Quality Control

Our Stachydrine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation (IR, NMR) to ensure it meets high-grade standards suitable for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming specifications for identity, purity, and impurities.

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 product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which may affect stability and handling properties.
