1,8-Dihydroxyanthraquinone, commonly known as Danthron or Chrysazin, is a naturally occurring dihydroxylated anthraquinone derivative that occupies a significant niche in both therapeutic medicine and industrial organic synthesis. Structurally related to the bioactive aglycones found in botanical laxatives like Senna and Rhubarb, it has been traditionally utilized as a stimulant laxative that increases the motility of the large intestine. Beyond its clinical history, it serves as a vital organic intermediate for the production of diverse vat dyes and pigments, where its specific phenolic arrangement allows for complex molecular coupling. In modern chemical research, it is valued as a scaffold for developing DNA-binding agents and fluorescent probes due to its planarity and unique electronic properties. By adhering to rigorous purity standards, 1,8-Dihydroxyanthraquinone enables the precise synthesis of high-value colorants and pharmaceutical research molecules.

Exposure to direct light can cause degradation of the crystalline structure and darkening of the color
In many jurisdictions (including the USA and parts of Europe), Danthron use is restricted to specific clinical cases, such as palliative care, due to concerns regarding its potential genotoxicity and long-term safety profile. It is largely replaced by Senna-based products for general constipation.
While both are dihydroxyanthraquinones, Chrysazin has hydroxyl groups at the 1 and 8 positions, whereas Alizarin has them at the 1 and 2 positions. This difference in substitution significantly changes their dyeing properties and clinical activity.
Small proprotions in various plants like Rhubarb and Aloe. However, for industrial and pharmaceutical use, it is typically synthesised for higher purity and consistency.
Phenolic hydroxyl groups deprotonate in basic conditions, resulting in a strong bathochromic shift (the color typically changes from orange to a deep violet or red), which is why it is often used as a pH-sensitive reagent.
