Description
4-Aminophenol (123-30-8) is the organic compound with the formula H2NC6H4OH, belongs to the class of organic compounds known as aniline and substituted anilines. Typically available as a white powder, it was commonly used as a developer for black-and-white film, marketed under the name Rodinal. Reflecting its slightly hydrophilic character, the white powder is moderately soluble in alcohols and can be recrystallized from hot water. In the presence of a base, it oxidizes readily. The methylated derivatives N-methylaminophenol and N,N-dimethylaminophenol are of commercial value. The compound is one of three isomeric aminophenols, the other two being 2-aminophenol and 3-aminophenol. 4-Aminophenol is a white or light yellow-brown crystals. It is slightly soluble in water and ethanol but insoluble in benzene and chloroform. It will quickly exhibit brown color after being dissolved in alkaline solution.

Application
1. The product is the intermediate of pharmaceutical intermediates, dyes and other fine chemicals. It can be used for the production of paracetamol, azo dyes, sulfur dyes, acid dyes, fur dye and developer, antioxidants as well as oil additive.
2. 4-Aminophenol is widely used in the synthesis of pharmaceuticals, dyes and other organic products and is mainly for the synthesis of paracetamol, clofibrate ketone, vitamin B1 and compound nicotinamide. It can be used for the production of Sulphur Blue FBG and weak acid dyes such as yellow 5G.
3. 4-Aminophenol is used as a dye for textiles, hair, furs and feathers, and is also used as a developing agent in photography for creating black and white images. It acts as a corrosion inhibitor in paints and as anti-corrosive lubricating agent in 2-cycle engines. It is also used as a wood stain, giving rose-like colour to timber. p-Aminophenol is one of key ingredients for synthesis of rubber antioxidants. Moreover, it is often used as a reagent for analysing metals like Copper, Magnesium, Vanadium and Gold, compounds like Nitrites and Cyanates, and antioxidants.
Storge & Handling
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. The floor of the storageroom must be impermeable to prevent the escape of liquids.
