3-(3,4-Dihydroxyphenyl)-1-methoxy-1-oxopropan-2-aminium chloride

In the title compound, C₁₀H₁₄NO₄⁺·Cl⁻, the benzene ring makes a dihedral angle of 64.68 (4)° with the methyl­amino­propano­ate unit, which is bonded to the catechol ring via a methyl­ene C atom. A strong intra­molecular O—H...O hydrogen bond occurs. In the crystal, O—H...O, N—H...Cl and O—H...Cl hydrogen bonds and weak C—H...O inter­actions link the mol­ecules into a three-dimensional network.
