Uses and applications

What the substance is used for, by industry and function

Dye intermediate, manufacture of p-aminosalicylic acid.

3-Aminophenol has been used as a stabilizer of chlorine-containing thermoplastics, although its principal use is as an intermediate in the production of 4-amino-2-hydroxybenzoic acid...This isomer is also employed as a hair colorant and as a coupler molecule in hair dyes.

Used as a chemical intermediate for the synthesis of: 7-amino-3-phenylcoumarin, p-aminosalicylic acid, desmedipham, flutolanil, formetanate hydrochloride, karbutilate, mepronil, phenmedipham.

Used in hair dyes in japan. Prepn may also be used to color other substances containing keratin.

Industrial uses: Monomers.

Use classes: Cosmetics, Pesticide transformation products.

Cosmetic ingredient, INCI name M-AMINOPHENOL(hair dyeing)

Functional uses

  • Dye

Cosmetic functions

  • Hair dyeing

How it is made

3-Aminophenol cannot be obtained easily by reduction. It is made mainly by the reaction of 3-aminobenzenesulfonic acid with sodium hydroxide or by the reaction of resorcinol with ammonia. Substitution of the sulfonic acid group in 3-aminobenzenesulfonic acid is accomplished by caustic soda fusion (5 - 6 hr, 240 - 245 °C). The product is purified by vacuum distillation. Alternatively, resorcinol reacts with ammonia, for example, in the presence of diammonium phosphate and arsenic pentoxide or ammonium sulfite to form 3-aminophenol. The compound also may be made by hydrolysis of 3-aminoaniline

Manufactured by redn of m-nitrophenol

Fusion of m-sulfanilic acid with caustic soda and subsequent extraction of the melt with ether.
