4-[N-(2-Hydroxy­ethyl)-N-methyl­amino]-N-isopropyl-1,8-naphthalimide

In the title crystal structure, C18H20N2O3, mol­ecules are linked into centrosymmetric dimers via O—H⋯O hydrogen bonds [H⋯O = 1.92 (3) A]. These dimers are, in turn, linked by weak C—H⋯O hydrogen bonds [H⋯O = 2.42 A], forming a two-dimensional network.
