The title compound, C 14 H 11 NO 5 S, is an ester of -naphthylsulfonic acid and N-hydroxysuccinimide. The N atom retains a flattened pyramidal geometry. The C atoms of the succinic ring are coplanar and the N atom is slightly displaced from their plane, leading to a pseudo-envelope conformation. The
