1-Naphthol, or α-naphthol, is a fluorescent organic compound with the formula C10H7OH. It is a white solid. It is an isomer of 2-naphthol differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologs of phenol, with the hydroxyl group being more reactive than in the phenols. Both isomers are soluble in simple alcohols, ethers, and chloroform. They are precursors to a variety of useful compounds. Naphthols (both 1 and 2 isomers) are used as biomarkers for livestock and humans exposed to polycyclic aromatic hydrocarbons.
Applications
1-Naphthol is a precursor to a variety of insecticides including carbaryl and pharmaceuticals including nadolol as well as for the antidepressant sertraline and the anti-protozoan therapeutic atovaquone. It undergoes azo coupling to give various azo dyes, but these are generally less useful than those derived from 2-naphthol.
Other uses
1-Naphthol is used in each of the following chemical tests:
Molisch’s test gives a red- or purple-colored compound to indicate the presence of carbohydrates.
The rapid furfural test turns purple quickly (<30s) if fructose is present, distinguishing it from glucose.
The Sakaguchi test turns red to indicate the presence of arginine in proteins.
The Voges–Proskauer test changes color from yellow to red to indicate that glucose is being broken down into acetoin which is used by bacteria for external energy storage.
