Quality Control

Our Picroside II is produced under strict quality management protocols. Each batch undergoes rigorous identity confirmation and purity analysis via advanced chromatographic and spectroscopic techniques to ensure it meets the high standards required for research and analytical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and identification results is provided with every shipment.

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) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
