4-[2-(4-Nitrophenyl)diazenyl]-1-naphthalenol

Description:
4-[2-(4-Nitrophenyl)diazenyl]-1-naphthalenol, also known by its CAS number 5290-62-0, is an organic compound characterized by its azo structure, which features a diazo group (-N=N-) linking a 4-nitrophenyl moiety to a naphthalenol unit. This compound typically exhibits a vibrant color due to the presence of the azo group, which is known for its ability to absorb visible light, making it useful in dye applications. The presence of the nitro group on the phenyl ring contributes to its electron-withdrawing properties, influencing its reactivity and stability. Additionally, the hydroxyl group (-OH) on the naphthalene ring can participate in hydrogen bonding, affecting solubility and interaction with other molecules. This compound may be used in various applications, including as a dye or pigment in textiles and other materials, as well as in research settings for studying azo compounds and their derivatives. Safety considerations should be taken into account due to the potential toxicity of nitroaromatic compounds.
