Quality Control

Our 2-(1-Naphthyl)Ethanesulfonyl Chloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets high-purity standards suitable for research and industrial synthesis. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical quality parameters. Our quality system is designed to support applications requiring traceability and consistent performance.

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, oxidizing agents, and sources of ignition.
