Quality Control

Every batch of 3-(3-Sulfonatopropyl)-2-Methylbenzoselenazol-3-Ium is produced and tested under strict quality management protocols to ensure consistency and purity for research and industrial use. Our standard grade typically meets a high purity specification, verified by advanced chromatographic and spectroscopic methods. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with each shipment. We support custom synthesis and can tailor specifications to meet specific project requirements, including research-grade and high-purity standards.

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 tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants or an inert atmosphere.
