1-Naphthol, or α-naphthol, is a organic compound with the formula C 10 H 7 OH. It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol. Both isomers are soluble in simple organic solvents. They are precursors ...

The drug has been marketed under the name “NRG-1,” although only a minority of samples of substances sold under this name have been found to actually contain naphyrone, [7] [8] [9] and even samples that proved to contain genuine β-naphyrone were in some cases also found to contain the 1-naphthyl isomer α-naphyrone in varying proportions ...
N-(1-Naphthyl)ethylenediamine is an organic compound. It is commercially available as part of Griess reagents, which find application in quantitative inorganic analysis of nitrates , nitrite and sulfonamide in blood, using the Griess test .
The sulfonic acid derivatives of 1-naphthylamine are used for the preparation of azo dye.These compounds possess the important property of dyeing unmordanted cotton.. An important derivative is naphthionic acid (1-aminonaphthalene-4-sulfonic acid), which is produced by heating 1-naphthylamine and sulfuric acid to 170–180 °C in the presence of crystallized oxalic acid.
Carbaryl is often inexpensively produced by direct reaction of methyl isocyanate with 1-naphthol. [5]C 10 H 7 OH + CH 3 NCO → C 10 H 7 OC(O)NHCH 3. Alternatively, 1-naphthol can be treated with excess phosgene to produce 1-naphthyl chloroformate, which is then converted to carbaryl by reaction with methylamine. [5]
1-Naphthaleneacetic acid (NAA) is an organic compound with the formula C 10 H 7 CH 2 CO 2 H. This colorless solid is soluble in organic solvents. This colorless solid is soluble in organic solvents. It features a carboxylmethyl group (CH 2 CO 2 H) linked to the "1-position" of naphthalene .
N,N-Dimethyl-1-naphthylamine is an aromatic amine. It is formally derived from 1-naphthylamine by replacing the hydrogen atoms on the amino group with methyl groups . N , N -Dimethyl-1-naphthylamine is used in the nitrate reductase test to form a precipitate of a red azo dye by reacting with a nitrite - sulfanilic acid complex.
