1,4-naphthoquinone
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.

Natural vitamin K is a derivative of 1,4-naphthoquinone. It is a planar molecule with one aromatic ring fused to a quinone subunit. 1,4-naphathoquinone itself has some vitamin K activity.
