Quality Control

Our 1-Naphthalenecarbonyl Chloride,2-Hydroxy- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for sensitive synthetic applications. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, ensuring traceability and consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
