Quality Control

Our Staunoside D is produced and tested under a strict quality management system. Each batch is analyzed using advanced chromatographic techniques to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with detailed chromatographic data (HPLC/LC-MS) for traceability and regulatory compliance, supporting its use in research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and light-sensitive (store away from light); therefore, containers must be kept tightly sealed and desiccated after opening to maintain stability and purity.
