Product Introduction:

4-Aminophenol, also known as “p-hydroxyaniline”, is an organic compound with a chemical formula of C6H7NO. 4-Aminophenol is a white crystal at room temperature. It has strong reducing properties and is easily oxidized by oxygen in the air. It turned grayish brown in the air.

4-Aminophenol is an intermediate for the synthesis of paracetamol, paracetamol, anomin, vitamin B1, nicotinamide, etc.

At present, the product is often used as an intermediate of fine chemicals such as medicine and dyes.

Uses of 4-Aminophenol:

4-Aminophenol can be widely used in the synthesis of medicines, dyes, rubber additives, photosensitive materials, oil antioxidants, hair dyes, vinyl monomer polymerization inhibitors and many other fine chemicals.

  1. Application in the pharmaceutical industry
    • As a pharmaceutical intermediate, 4-aminophenol can be used to synthesize paracetamol (acetaminophen), paracetamol (paracetamol acetylsalicylate), propranolol, compound nicotinamide, salanol, antomin, vitamin B1 Waiting for drugs.
  2. Application in the rubber industry
    • 4-aminophenol can synthesize p-phenylenediamine rubber antioxidant H, 4010, 4010NA, 4030, 4020, etc.
  3. Application in the dye industry
    • 4-Aminophenol is mostly used in the synthesis of sulfur dyes, acid dyes, azo dyes and fur dyes. Such as: sulfur blue FBG, sulfur brilliant green and so on.
  4. Application in other industries
    • 4-Aminophenol has strong reducibility. In the synthesis of other fine and specialty chemicals, 4-(N-methylamino)phenol and its salts are synthesized from p-aminophenol.
    • It can be used as a photographic developer, and can also inhibit the corrosion of steel by chloride-containing acid solutions, and can be used as an intermediate for hair dyes.
    • Synthetic 4-anilinophenol can be used as antioxidant and vinyl monomer polymerization inhibitor for petroleum and lubricating oil, etc.

Toxicity and Protection:

Toxic, 4-Aminophenol has the dual toxicity of aniline and phenol.
