Quality Control

Our production of 1-Hydroxynaphthalene-2-Carbonyl Chloride adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. The material is characterized using advanced analytical techniques including HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

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 or argon) to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
