Quality Control

Our 1,4-Diamino-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonic Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. We provide comprehensive Certificates of Analysis (COA) detailing key specifications such as assay, impurity profile, and sulfonic acid content. Our quality commitment ensures the material meets the exacting standards required for sensitive dye synthesis and other fine chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature (store away from light), prolonged exposure to direct light should be avoided to maintain product integrity.
