Quality Control

Our 1-Amino-7-Naphthol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) upon request, which include results from HPLC, IR spectroscopy, and other relevant tests to verify compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from strong oxidizing agents.
