Naphthol

Naphthol, also known as naphthalen-1-ol, is a type of hydroxynaphthalene. It is an organic compound that is derived from naphthalene. There are two isomers of naphthol, differentiated by the location of the hydroxyl group on the naphthalene ring. These are 1-naphthol and 2-naphthol, and both are colorless crystalline solids.

Structure and Synthesis

Naphthols are naphthalene homologues of phenol, with the hydroxyl group being attached to one of the carbon atoms in the naphthalene ring. They are produced by a process known as alkylation, in which a naphthol is combined with an alkyl group.

Uses

Naphthols are used in the manufacture of certain dyes and are also precursors to a variety of useful compounds. They are commonly used in the synthesis of certain azo dyes. Naphthols can also be used as an antioxidant in various industries, including the rubber, textile, and paper industries.

Health Effects

Exposure to naphthol can cause a variety of health effects, including skin and eye irritation, respiratory problems, and in severe cases, damage to the liver and kidneys. It is considered a potential carcinogen by the International Agency for Research on Cancer.
