Quality Control

Our 5-Hydroxyanthranilic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing specifications such as assay, related substances, and residual solvents, supporting compliance with research and cGMP-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
