Quality Control

Our Rhododendrin is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR, to ensure it meets stringent specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and compliance with customer requirements for research and production use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
