Quality Control

Every batch of 3-Oxo-5-Indanesulfonoyl Chloride is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and process chemistry. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles by HPLC, NMR, and IR is supplied with each shipment to guarantee reproducible results and supply chain reliability.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and oxidizing agents.
