Description

2-Amino-6-ethyl-3,5,7,8-tetrahydroxy-1,4-dihydronaphthalene-1,4-dione belongs to the class of organic compounds known as naphthoquinones. Naphthoquinones are compounds containing a naphthohydroquinone moiety, which consists of a benzene ring linearly fused to a bezene-1,4-dione (quinone). Echinamine A is found in Scaphechinus mirabilis. 2-Amino-6-ethyl-3,5,7,8-tetrahydroxy-1,4-dihydronaphthalene-1,4-dione is an extremely weak basic (essentially neutral) compound (based on its pKa).
