Quality Control

Our n-Hydroxy-1-Naphthylamine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing specific batch results is provided with every shipment to guarantee traceability and consistent quality.

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 property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
