910dihydroxyanthracene

9,10-dihydroxyanthracene, also known as anthrarufin, is an organic compound with the chemical formula C14H10O2. It is a derivative of anthracene, a polycyclic aromatic hydrocarbon, where two hydroxyl (-OH) groups are substituted at the 9 and 10 positions. Anthrarufin appears as a yellow to orange crystalline solid.

This compound is one of several dihydroxyanthracene isomers, distinguished by the placement of its hydroxyl groups. It is known for its fluorescent properties, emitting light when exposed to ultraviolet radiation. Anthrarufin has found some applications as a chemical intermediate, particularly in the synthesis of dyes and pigments. Its presence can also be detected in some natural sources, though it is not a widely abundant natural product.

The synthesis of anthrarufin typically involves oxidation reactions of anthracene derivatives. Its chemical reactivity is influenced by the presence of the hydroxyl groups and the aromatic anthracene core, allowing for further chemical modifications. While not a major industrial chemical, its specific properties make it relevant in niche areas of organic chemistry and materials science.
