1-Naphthol
1-Naphthol, or ?-naphthol, is a colorless crystalline solid with the formula C10H7OH. It is an isomer of 2-naphthol differing by the location of the hydroxyl group on naphthalene. The naphthols are naphthalene homologues of phenol, with the hydroxyl group being more reactive than in the phenols. Both isomers are soluble in simple alcohols, ethers, and chloroform. They can be used in the production of dyes and in organic synthesis.; 1-naphthol (1N) is a metabolite of carbaryl and naphthalene that is an intermediate in Metabolism of xenobiotics by cytochrome P450. It is generated by spontaneous reaction from (1R,2S)-Naphthalene epoxide then is it converted to 1,4-Dihydroxynaphthalene. Although 1-Naphthol is not persistent in the body, a single urine sample may adequately predict exposure over several months to chlorpyrifos, which is a broad-spectrum organophosphate insecticide. In adult men, TCPY and 1N were associated with reduced testosterone levels (PMID: 16357596, 15579421). Naphthalen-1-ol is found in black walnut. 1-naphthol (1N) is a metabolite of carbaryl and naphthalene that is an intermediate in Metabolism of xenobiotics by cytochrome P450.

2-Naphthol
2-Naphthol is a colorless crystalline solid and an isomer of 1-naphthol, differing by the location of the hydroxyl group on naphthalene. The naphthols are naphthalene homologues of phenol, with the hydroxyl group being more reactive than in the phenols. 2-Naphthol has several different uses including dyes, pigments, fats, oils, insecticides, pharmaceuticals, perfumes, antiseptics, synthesis of fungicides, and antioxidants for rubber. Detection of 2-Naphthol in urine usually results from long-term persistent exposure to pesticides such as chlorpyrifos, but also due to exposure to naphthalene in older types of mothballs, fires that produce polyaromatic hydrocarbons (PAHs), and tobacco smoke.

Naphthalene epoxide
Naphthalene epoxide is an epoxide derivative of naphthalene. The toxicity of naphthalene has to do with the Phase I metabolism of this compound by cytochrome P450 monooxygenases. Deactivation of naphthalene involves epoxidation followed by glutathione conjugation and mercapturic acid formation. Naphthalene is stereoselectively metabolized to form (1R,2S)-Naphthalene epoxide and (1S,2R)-Naphthalene epoxide in the presence of CYP1A1 and CYP1A2, CYP2E1,CYP3A4 and CYP2A6.
