3-Methoxy-3-oxopropanaminium chloride
In the title compound, C(4)H(10)NO(2) (+)·Cl(-), the central ethyl-ene bond of the cation adopts a gauche conformation. The three H atoms of the -NH(3) (+) group are engaged in strong and highly directional inter-molecular N-H⋯Cl hydrogen bonds, which result in a tape-like arrangement along [010] of the respective ion pairs. In addition, weak inter-molecular C-H⋯Cl and C-H⋯O inter-actions are p...
متن کامل3-(3,4-Dihydroxyphenyl)-1-methoxy-1-oxopropan-2-aminium chloride
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.
متن کامل1-(3-Oxo-3-phenylpropyl)piperidinium chloride
In the title salt, C14H20NO(+)·Cl(-), the piperidine ring adopts a chair conformation. In the crystal, the cations and anions are linked by classical N-H⋯Cl hydrogen bond and weak C-H⋯Cl and C-H⋯O hydrogen bonds; the C-H⋯O hydrogen bonds exhibit R 2 (2)(14) ring motifs while the C-H⋯Cl hydrogen bonds link the mol-ecules into chains along the a-axis direction. π-π stacking is observed between pa...
متن کامل3-Methoxy-4-(4-nitrobenzyloxy)benzaldehyde
In the title compound, C(15)H(13)NO(5), the vanillin group makes a dihedral angle of 4.95 (8)° with the benzene ring of the nitro-benzene group. The packing is stabilized by weak, non-classical inter-molecular C-H⋯O inter-actions which link mol-ecules into chains running along the c axis.
متن کاملEvaluation of plasma 3-methoxy-4-hydroxyphenylglycol.
A high-performance liquid chromatographic (HPLC) assay suitable for the evaluation of 3-methoxy-4-hydroxyphenylglycol (MHPG) in 1-ml aliquots of plasma is presented. Preparatory steps include extraction into ethyl acetate and minicolumn chromatography. Recoveries are monitored with [3H]MHPG. The HPLC procedure utilizes a C18 column, isocratic elution and amperometric detection. The assay was ch...
