Description

General description

1-Naphthol, a metabolite of carbaryl and naphthanlene. It is formed by spontaneous reaction from (1R, 2S)-Naphthalene epoxide followed to form 1, 4-Dihydroxynaphthalene.

Application

1-Naphthol may be used as a reference standard for the determination of 1-naphthol:

• In human urine by a rapid and automated method based on coupled-column liquid chromatography (LC-LC) with fluorescence detection.
• In canned fruit juices by reversed-phase high performance liquid chromatography with diode-array detection.
