Quality Control

Our 4,4-Dimethyl-5α-Cholesta-7,9(11)-Dien-3β-Ol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR). We provide Certificates of Analysis (COA) with every shipment, detailing all relevant specifications to ensure compliance with your research and development 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 hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
