N-Phenylnaphthalen-1-amine (NPN) is an aromatic amine with the chemical formula C 16 H 12 NH. This molecule is notable for its binding affinity in mouse major urinary ...
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.
[1] [2] [3] It is a positional isomer of 2-naphthylaminopropane (2-NAP; PAL-287). [1] [2] [3] 2-NAP and derivatives like methylnaphthylaminopropane (MNAP) are known to be potent serotonin–norepinephrine–dopamine releasing agents (SNDRAs) and/or serotonin receptor agonists, whereas 1-NAP has not been assessed in these regards.
NpP 2 S 4 is a compound related to Lawesson's reagent formed by the reaction of 1-bromonaphthalene with P 4 S 10, [1] this is a 1,3,2,4-dithiadiphosphetane 2,4-disulfide which has a naphth-1,8-diyl group holding the two phosphorus atoms together.
reduction of 1-nitroonaphthalene-8-sulfonic acid, precursor to C.I. Acid Blue 113 Notes: Peri-acid dehydrates to the sultam . Via the Bucherer reaction , heating periacid with anilinium salts gives the N-phenyl derivative, precursor to Acid Blue 113.
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.
The bonds C1−C2, C3−C4, C5−C6 and C7−C8 are about 1.37 Å (137 pm) in length, whereas the other carbon–carbon bonds are about 1.42 Å (142 pm) long. This difference, established by X-ray diffraction , [ 21 ] is consistent with the valence bond model in naphthalene and in particular, with the theorem of cross-conjugation .
A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings.Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [1] or when biomass burns at lower temperatures as in forest fires.
