Quality Control

Our 1α,3β,11α-Trihydroxy-5α-Ergost-24(28)-En-18-Oic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and specific tests for residual solvents and moisture content. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or manufacturing specifications.

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. For long-term storage, consider using desiccants.
