Basic Information
Product Name: p-Aminophenol, 4-Aminophenol
Chemical Formula: C6H7NO
CAS No. : 123-30-8
Appearance and Properties: It is a white or light gray crystalline powder, which easily turns brown in the air or when exposed to light.
Melting Point: 186 - 189ºC
Density: Relative density (water=1) 1.29 (25ºC)
Solubility: Slightly soluble in cold water, easily soluble in hot water, ethanol, ether, acetone and alkaline solutions, and hardly soluble in benzene and chloroform.
Uses
Pharmaceutical Field: It is an important intermediate for the synthesis of drugs such as paracetamol and clofibrate. Paracetamol is a commonly used antipyretic and analgesic drug. Through a series of chemical reactions, p - aminophenol is converted into paracetamol, which is used to relieve symptoms such as fever, headache and joint pain.
Dye Industry: It can be used to manufacture azo dyes, sulfur dyes, etc., such as Direct Fast Black G. These dyes are widely used in the dyeing process of textile and leather industries.
Rubber Additives: As a rubber antioxidant, it can improve the anti - aging performance of rubber products and prolong their service life. For example, adding p - aminophenol - based antioxidants to rubber products such as automobile tires can prevent the rubber from aging and cracking due to long - term exposure to the air or being affected by heat, oxygen and other factors.
Other Aspects: It is also used to prepare developers, antioxidants, petroleum additives, etc., and has important applications in the chemical, electronic, petroleum and other fields. In the photography industry, p - aminophenol can be used as one of the components of black - and - white developers to participate in the development process, converting the latent image on the film into a visible image.
Safety Information
Hazard Class: Class 6.1 Toxic Substances.
Hazard Characteristics: Flammable when exposed to open fire and high heat. It decomposes under high heat to release toxic gases. It can react with strong oxidants.
Health Hazards: Harmful if inhaled, ingested or absorbed through the skin. It has an irritating effect on the eyes, skin, mucous membranes and respiratory tract. Long - term exposure may cause methemoglobinemia, resulting in tissue hypoxia.
When using and storing p - aminophenol, safety operating procedures should be strictly followed and necessary protective measures should be taken, such as wearing protective glasses, gloves and masks, to avoid contact with skin and eyes and prevent inhalation of dust. At the same time, it should be stored in a cool and ventilated warehouse, away from fire and heat sources, and separated from oxidants, acids, etc. to avoid mixed storage.
