Quality Control

Every batch of 5-Chloro-1,2-Dihydro-1-Acenaphthylenol is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and fine chemical synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and impurity profiles as determined by advanced chromatographic and spectroscopic methods.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
