Naphthalene is an organic compound with formula C 10 H 8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. [15] As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings.
1-Naphthol, or α-naphthol, is an 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 ...
Sodium naphthalene is an organic salt with the chemical formula Na + [C 10 H 8] −. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic, and inorganic chemistry. It is usually generated in situ. When isolated, it invariably crystallizes as a solvate with ligands bound to Na +. [1]
2-Naphthol, or β-naphthol, is a fluorescent colorless (or occasionally yellow) crystalline solid with the formula C 10 H 7 OH. It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol, but more reactive.
The color intensity of the resulting solution is then measured by a colorimeter and checked against a calibration curve to determine the nitrite ion concentration. [ 4 ] To analyze nitrate concentrations quantitatively, the sample is first passed through a copper-cadmium column to reduce the nitrate ions quantitatively to nitrite ions, and the ...

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 .
This compound is used as a fluorescent molecular probe. [1] For example, ANS can be used to study conformational changes induced by ligand binding in proteins, as ANS's fluorescent properties will change as it binds to hydrophobic regions on the protein surface. Comparison of the fluorescence in the presence and absence of a particular ligand ...
