Quality Control

Our 17-p-Toluenesulfonylhydrazide (3β,5α)-Androstan-3-Ol is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for research and synthesis. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after the container has been opened. Keep away from heat, sparks, and open flame.
