Quality Control

Our (20α,22R,25S)-Spirosta-5-Ene-3β-Ol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC, IR, and melting point determination to ensure identity, purity, and conformity to specifications. Certificates of Analysis (COA) are provided with every shipment, detailing all test results. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
