2,2′-Dihydroxyazobenzene

Description:
2,2′-Dihydroxyazobenzene, also known as 4,4′-dihydroxyazobenzene, is an organic compound characterized by its azo group (-N=N-) linking two aromatic rings, each bearing a hydroxyl (-OH) group at the para position. This compound is typically a solid at room temperature and exhibits a deep orange to red color, which is common for azo compounds due to their conjugated double bond system. It is soluble in organic solvents and has limited solubility in water. The presence of hydroxyl groups enhances its reactivity, allowing it to participate in various chemical reactions, including coupling reactions and oxidation. 2,2′-Dihydroxyazobenzene is often used as a dye intermediate and in the synthesis of other organic compounds. Additionally, it has applications in the field of analytical chemistry, particularly in colorimetric assays. However, it is important to handle this compound with care, as some azo compounds can be toxic or carcinogenic under certain conditions.
