title: 3-(3,4-Dihydroxyphenyl)-1-methoxy-1-oxopropan-2-aminium chloride.
abstract: In the title compound, C(10)H(14)NO(4) (+)·Cl(-), the benzene ring makes a dihedral angle of 64.68 (4)° with the methyl-amino-propano-ate unit, which is bonded to the catechol ring via a methyl-ene C atom. A strong intra-molecular 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 inter-actions link the mol-ecules into a three-dimensional network.
