Quality Control

Our 6-Methoxy-2-Naphthalenesulfonyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. Production adheres to cGMP guidelines where applicable, and each lot is accompanied by a comprehensive Certificate of Analysis (COA). The COA provides detailed results for identity, purity (typically >98% by HPLC), and impurity profile, ensuring it meets the stringent requirements for pharmaceutical R&D and production.

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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent decomposition. Keep away from strong acids and incompatible materials.
