Quality Control

Every batch of Indan-5-Ylmethanesulfonyl Chloride is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

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 degradation. Keep away from strong bases and oxidizing agents.
