1-Chloronaphthalene is an aromatic compound. It is a colorless, oily liquid which may be used to determine the refractive index of crystals by immersion.
This toxic, nonpolar organochlorine compound is sometimes used as a powerful biocide, and is also known as Basileum. It occasionally serves as insecticide and fungicide in the timber floors of shipping containers, where it fulfills the same role as chlordane.
