Quality Control

Our 1-Amino-4-Methylamino-9,10-Dioxo-9,10-Dihydroanthracene-2-Carboxylicacidmethylester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive synthesis processes. Certificates of Analysis (COA) documenting all critical quality parameters are available upon request to support your quality assurance protocols.

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). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be kept in the original packaging or amber glass until use.
