Quality Control

Our 9,10-Dihydro-9,10-Dioxo-3-Phenanthrenesulfonic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
