The most common current use for naphthalene is as a raw material in the production of phthalic anhydride, which is often used in the production of dyes, plasticizers, insecticides and some pharmaceutical products. In the past, naphthalene was used as a fumigant for repelling moths, for which it is popularly known as mothballs.
