(4-Hydroxy-3-nitrobenzyl)methylammonium chloride

The title compound, C8H11N2O3+·Cl , was synthesized as an intermediate in the development of a new sugar sensor. The structure displays N—H...Cl and O—H...O hydrogen bonding, as well as weak O—H...Cl interactions and π–π stacking (3.298 ). There are two formula units in the asymmetric unit.
