Quality Control

Every batch of 2-(2,11-Dihydroxyundecyl)Aminoethanethiol 1-Sulfate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure identity, purity, and consistency for your critical applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting key parameters such as assay, impurity profile, and physical characteristics.

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 and easily oxidized nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to minimize moisture uptake and oxidative degradation.
