Quality Control

Our 1,2,5,6-Naphthalenetetramine Tetrahydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting research and industrial grade standards. A detailed Certificate of Analysis (COA) providing batch-specific results is available upon request to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
