Quality Control

Our N-(1-Naphthyl)Ethylenediamine Dihydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification (IR), assay (HPLC/Titration), and tests for specific impurities, to ensure it meets high-purity standards suitable for analytical applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with specified parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
