naphthol

 [naf´thol]
a phenol occurring in coal tar in two forms: α- or 1-naphthol and β- or 2-naphthol. It is used in dyes, insecticides, and pharmaceutical compounds. If excessive amounts are ingested, poisoning may result, characterized by anemia, jaundice, convulsions, and coma.

naph·thol

(naf'thol),
A hydroxynaphthalene, occurring in two forms: α-naphthol, a dye intermediate used in cytochemistry for l-arginine localization; and β-naphthol, also known as isonaphthol, used as an anthelmintic and antiseptic. Both forms are also used in the manufacture of dyes, organic chemicals, and rubber products.
Synonym(s): naphthalenol

In this data set, smoking status is significantly associated with preexposure urinary naphthol levels but not with postexposure urinary naphthol levels.

Only urinary naphthols were adjusted for creatinine, and all statistical tests were repeated with and without adjustment.
Concentrations of naphthalene and the naphthols were also 2-fold higher in the moderate-exposure group than the low-exposure group.
9%, respectively, in postexposure samples when naphthols were adjusted for urinary creatinine (data not shown).
We observed much lower levels of naphthalene in urine than those of the naphthols, which is not surprising because relatively small amounts (< 1-2%) of unmetabolized aromatic compounds are eliminated in urine (Ghittori et al.
Previous studies suggested two-phase excretion kinetics for the naphthols in urine, consisting of a rapid phase with half-lives ([t.
