Quality Control

Our Bretschnoside A is manufactured under strict quality management systems. Each batch undergoes rigorous identity confirmation and purity analysis using advanced techniques including HPLC, NMR, and mass spectrometry to ensure it meets the high standards required for research and reference applications. A comprehensive Certificate of Analysis (COA) detailing purity, analytical methods, and batch-specific data 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 (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a desiccated environment to maintain stability and purity. For long-term storage, consider conditions under an inert atmosphere.
