Quality Control

Our production of (22R)-16β,18-Diacetoxy-4,22-Dihydroxycholest-4-En-3-One adheres to stringent quality protocols suitable for research and pharmaceutical intermediate applications. Each batch undergoes comprehensive analytical characterization, including HPLC for purity and NMR/IR for structural confirmation. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to ensure traceability and compliance with your project 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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or an inert atmosphere.
