Naphthalene is widely used as a precursor in the production of phthalic anhydride, a key ingredient in the manufacture of plastics, resins, and dyes. It is also commonly employed in the synthesis of insecticides, particularly mothballs, which protect clothing and fabrics from damage by moth larvae. In the chemical industry, naphthalene serves as a raw material for the production of surfactants and dispersants, which are essential in various industrial processes. Additionally, it is utilized in the creation of certain types of synthetic tanning agents for the leather industry. Its ability to sublimate makes it useful in air fresheners and deodorizers. Naphthalene derivatives are also explored in pharmaceutical research for developing new drugs.
