Naphthalene is a major component of some mothballs.It repels moths as well as some animals. [citation needed]Since mothballs that contain naphthalene are considered hazards, safer alternatives have been developed, such as the use of 1,4-dichlorobenzene, however, 1,4-dichlorobenzene has been declared as a potential neurotoxin. 1,4-dichlorobenzene has been linked to potentially causing ...
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.

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]

1,4-Naphthoquinone acts as strong dienophile in Diels-Alder reaction.Its adduct with 1,3-butadiene can be prepared by two methods: 1) long (45 days) exposure of naphthoquinone in neat liquid butadiene taken in huge excess at room temperature in a thick-wall glass tube or 2) fast catalyzed cycloaddition at low temperature in the presence of 1 equivalent of tin(IV) chloride: [5]
Naphthol yellow S is an organic compound that is a dye. It is a derivative of 1-naphthol . At one time it was a popular food colorant but it was delisted in 1959 in the U.S. [ 3 ]
