Square wave voltammetric determination of valproic acid in pharmaceutical Preparations
The electrochemical behavior of valproic acid (VAL) was investigated using square wave voltammetry, cyclic voltammetry, and sampled direct current polarography and a new square wave voltammetric method was developed for determination of VAL in pharmaceutical preparations. VAL showed two reduction peaks at about –0.2 V and –0.8 V vs. Ag/AgCl 3 M KCl with a hanging mercury drop electrode in 0.05 ...
متن کامل2,2-Dimethyl-5-[(2-nitroanilino)methylidene]-1,3-dioxane-4,6-dione
The crystal of the title compound, C(13)H(12)N(2)O(6), contains a bifurcated intra-molecular hydrogen bond between the N-H group and one of the O atoms from both the nitro group and the dioxane-4,6-dione moiety. In addition, mol-ecules are linked by a series of inter-molecular C-H⋯O secondary inter-actions. The dihedral angles between the benzene ring and the nitro group and the conjugated part...
متن کامل5-(4-Hydroxybenzylidene)-2,2-dimethyl-1,3-dioxane-4,6-dione
The title compound, C(13)H(12)O(5), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 4-hy-droxy-benz-alde-hyde in ethanol. The 1,3-dioxane ring is in a distorted boat conformation. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(20) rings.
متن کامل5-(4-Fluorobenzylidene)-2,2-dimethyl-1,3-dioxane-4,6-dione
The title compound, C(13)H(11)FO(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 4-fluoro-benz-alde-hyde in ethanol. The 1,3-dioxane ring adopts an envelope conformation. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کامل2,2-Dimethyl-5-[(3-nitroanilino)methylene]-1,3-dioxane-4,6-dione
The benzene ring of the title compound, C(13)H(12)N(2)O(6), is twisted away from the planes of the amino-methyl-ene unit and the dioxane ring by 30.13 (4) and 35.89 (4)°, respectively. The dioxane ring exhibits a half-boat conformation, in which the C atom between the dioxane O atoms is 0.553 (8) Å out-of-plane. An intra-molecular N-H⋯O hydrogen bond stabilizes the conformation of the dioxane r...
