Naphthol
Naphthol (pronunciation: /ˈnæf.θɔːl/ or /ˈnæf.θɒl/) is a term used in organic chemistry to refer to either of two isomeric phenolic compounds derived from naphthalene.
Etymology
The term "Naphthol" is derived from the name of the parent hydrocarbon, naphthalene, and the suffix "-ol" indicating its classification as an alcohol.
Chemistry
Naphthol consists of a naphthalene molecule with a hydroxyl group (OH) attached to one of the carbon atoms. There are two isomers of naphthol, differentiated by the location of the hydroxyl group: 1-naphthol and 2-naphthol. Both isomers are soluble in simple alcohols, ethers, and chloroform.
Uses
Naphthol is used in the synthesis of certain azo dyes and antioxidants for rubber. It is also used as an intermediate for the synthesis of a number of chemical compounds and pharmaceuticals.
