Quality Control

Our 3-Oxo-D:C-Friedours-7-En-28-Oic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. We provide a Certificate of Analysis (COA) with each shipment, detailing all specifications and test results to ensure compliance with your research or production requirements.

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 sensitivity to light and potential for oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep the container tightly sealed in a dry environment to minimize exposure to moisture.
