Quality Control

Every batch of Purpurosamine B is manufactured and tested under strict quality management systems. We provide material that meets high-purity standards suitable for research and pharmaceutical development. Comprehensive analytical testing, including HPLC, NMR, and MS, is performed to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting all critical quality attributes.

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 dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
