Quality Control

Our 3β,20β-Dihydroxyurs-12-En-28-Oic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and heavy metals to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing all specifications are 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). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect stability and purity.
