Quality Control

Our Para-Isothiocyanatobenzenesulfonate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your research and production standards.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation. Keep away from incompatible materials such as strong bases, amines, and oxidizing agents.
