Quality Control

Our Delphinidin-3-o-Arabinoside Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV), to ensure it meets the high standards required for research and analytical applications. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability, purity, and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a dry, cool place. This compound is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccant or inert atmosphere.
