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.
