Quality Control

Our Bis(2-Hydroxyethyl)-2-(2-Hydroxyethylthio)Ethylsulphide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by GC or HPLC and identification by FTIR, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
