Quality Control

Our 5α-Androstan-4β-Ol is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency, suitable for demanding research and synthesis applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to cGMP principles where applicable, and specifications can be aligned with client requirements for pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
