萘醌

Also known as naphthoquinone, α-naphthoquinone, 4a,8a-dihydronaphthalene-1,4-dione, 1,4-dihydro-1,4-diketonaphthalene, p-naphthoquinone, alpha-naphthoquinone

1,4-Naphthoquinone or para-naphthoquinone is a quinone derived from naphthalene. It forms volatile yellow triclinic crystals and has a sharp odor similar to benzoquinone. It is almost insoluble in cold water, slightly soluble in petroleum ether, and more soluble in polar organic solvents. In alkaline solutions it produces a reddish-brown color.
