Quality Control

Every batch of 3β-Hydroxy-5α-Pregnan-20-One Sulfate Pyridine Salt is manufactured and tested under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC for purity and spectroscopic methods for structural confirmation, to ensure compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment.

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 sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
