Quality Control

Our 3,3-Dichloro-2-Oxoindoline-5-Sulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and production. Certificates of Analysis (COA) with full traceability are provided for every shipment.

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). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; therefore, it must be kept under an inert atmosphere (e.g., nitrogen or argon) in a desiccator to prevent degradation. Keep away from incompatible materials such as bases, amines, and alcohols.
