Quality Control

Our Thujopsenic Acid is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis including identification (IR, NMR), purity determination (HPLC), and specific impurity profiling to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all test results are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
