Quality Control

Our (22R,23R)-2α,3α,22,23-Tetrahydroxy-B-Homo-7-Oxa-5α-Ergost-24(28)-En-6-One is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral purity and spectroscopic identification (NMR, IR, MS), to ensure identity, strength, and composition. Certificates of Analysis (COA) detailing all specifications are provided to guarantee traceability and compliance with your research or 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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment. For long-term storage, consider storing under an inert atmosphere to prevent potential oxidation.
