mhydroxyaniline

m-Hydroxyaniline is an organic compound with the chemical formula C6H7NO. It is a derivative of aniline, where a hydroxyl group (-OH) is substituted at the meta position (position 3) of the benzene ring. This compound is a colorless to light yellow liquid at room temperature, with a characteristic amine odor. It is soluble in water and most organic solvents.

m-Hydroxyaniline is primarily used as an intermediate in the synthesis of various dyes, pigments, and pharmaceuticals. It is also used in the production of antioxidants and as a corrosion inhibitor in metalworking fluids. Additionally, it has been studied for its potential applications in the field of materials science, particularly in the development of conductive polymers.

The synthesis of m-hydroxyaniline typically involves the nitration of aniline followed by reduction of the nitro group to an amino group. Alternatively, it can be prepared by the meta-hydroxylation of aniline using various oxidizing agents.

m-Hydroxyaniline is a hazardous substance. It can cause skin and eye irritation, and inhalation of its vapors can lead to respiratory irritation. It is also toxic if ingested or absorbed through the skin. Proper safety measures, including the use of personal protective equipment and ventilation, should be taken when handling this compound.
