Quality Control

Our 2A,3A,16A,17A-Diepoxy-17B-Acetoxy-5A-Androstane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and specific tests for residual solvents and related substances. Certificates of Analysis (COA) detailing all specifications and test results are provided to ensure full traceability and compliance with your research or cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and opened under inert atmosphere when necessary for prolonged handling to maintain stability and purity.
