CAS 1689-82-3

4-Hydroxyazobenzene

Description:

4-Hydroxyazobenzene, with the CAS number 1689-82-3, is an organic compound characterized by its azo group (-N=N-) linking two aromatic rings, specifically a phenolic hydroxyl group (-OH) attached to one of the benzene rings. This compound appears as a yellow to orange solid and is known for its use as a dye and in various chemical applications, including as a pH indicator due to its ability to change color in response to pH variations. It exhibits moderate solubility in organic solvents and limited solubility in water. The presence of the hydroxyl group contributes to its reactivity, allowing for further chemical modifications. 4-Hydroxyazobenzene is also of interest in research related to azo compounds and their potential environmental and health impacts, as some azo dyes can be metabolized into carcinogenic amines. Safety precautions should be taken when handling this compound, as it may pose health risks upon exposure.
