Quality Control

Our 5-Chloro-6-Ethoxynaphthalene-2-Sulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with detailed batch-specific data are available upon request to support your quality assurance and regulatory documentation needs.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and incompatible materials.
