CAS 104-91-6: 4-Nitrosophenol

Description:4-Nitrosophenol, with the CAS number 104-91-6, is an organic compound characterized by the presence of both a nitroso group (-NO) and a hydroxyl group (-OH) attached to a benzene ring. It appears as a yellow to orange crystalline solid and is known for its distinctive aromatic odor. The compound is soluble in organic solvents but has limited solubility in water. 4-Nitrosophenol exhibits properties typical of nitrophenols, including acidity due to the hydroxyl group, and it can participate in various chemical reactions, such as electrophilic substitution. It is often used in organic synthesis and as an intermediate in the production of dyes and pharmaceuticals. However, it is important to handle this compound with care, as it may pose health risks, including potential toxicity and environmental hazards.
