Quality Control

Our 3-Aminophenol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and titration methods, to ensure it meets high-purity standards suitable for industrial and fine chemical applications. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from strong oxidizing agents, strong acids, and strong bases. For long-term storage, consider an inert atmosphere (nitrogen or argon) to maintain product integrity.
