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 .  As an   aromatic   hydrocarbon , naphthalene's structure consists of a fused pair of   benzene   rings. It is best known as the main ingredient of traditional   mothballs .

Naphthalene is used mainly as a precursor to other chemicals. The single largest use of naphthalene is the industrial production of  phthalic anhydride , although more phthalic anhydride is made from  o -xylene . Many  azo dyes  are produced from naphthalene, and so is the  insecticide   1-naphthyl- N -methylcarbamate ( carbaryl ) . Other useful  agrichemicals  include naphthoxyacetic acids.

Naphthalenesulfonic acids and sulfonates
Many  naphthalenesulfonic  acids and sulfonates are useful. Alkyl naphthalene sulfonate are  surfactants , The  aminonaphthalenesulfonic acids , naphthalenes substituted with  ethers  and  sulfonic acids , are intermediates in the preparation of many synthetic  dyes . 

Wetting agent and surfactant
Alkyl naphthalene sulfonates (ANS) are used in many industrial applications as nondetergent  wetting agents  that effectively disperse colloidal systems in aqueous media. The major commercial applications are in the agricultural chemical industry, which uses ANS for wettable powder and wettable granular (dry-flowable) formulations, and the textile and fabric industry, which utilizes the wetting and defoaming properties of ANS for bleaching and dyeing operations.

Other uses
It is used in pyrotechnic special effects such as the generation of black smoke and simulated explosions.  It is used to create artificial pores in the manufacture of high-porosity grinding wheels.
