In the title mol-ecular salt, C(15)H(17)N(2)O(+)·Br(-), the benzene and pyridinium rings form a dihedral angle of 83.0 (1)°. In the crystal, N-H⋯Br and N-H⋯O hydrogen bonds link the components into chains along [010]. These chains are linked by weak C-H⋯O and C-H⋯Br hydrogen bonds, forming a three-dimensional network.

The title mol-ecular salt, C13H15N2 (+)·Br(-), crystallized with two independent ion pairs (A and B) in the asymmetric unit. In the cations, the planes of the pyridine and benzene rings are inclined to one another by 79.32 (8) and 82.30 (10)° in ion pairs A and B, respectively. In the crystal, the anions and cations are connected by N-H⋯Br hydrogen bonds, forming a centrosymmetric tetra-mer-lik...

The interactions of an anionic redox-active dye Alizarin Red S (ARS) with novel N-hydroxyethyl-3-alkyloxypyridinium surfactants 1-(2-hydroxyethyl)-3-(tetradecyloxy)pyridinium bromide, [HEC14OPyBr], and 1-(2-hydroxyethyl)-3-(hexadecyloxy)pyridinium bromide, [HEC16OPyBr], were investigated in an aqueous solution for the first time with an attempt to obtain comprehensive knowledge of oppositely ch...

In order to improve the homogeneity and dispersity of the sericite in methylphenyl-silicone resin, the agglomerate state of the sericites was controlled effectively. The dispersive model of the sericite in methylphenyl-silicone resin was designed also. First, the modified sericite was prepared using hexadecyl trimethyl ammonium bromide as the intercalating agent. Then, functional sericite was i...

Binding studies of cationic detergents such as cetyltrimethyl ammonium bromide, Cetyl pyridinium bromide and dodecyl trimethyl ammonium bromide with β Lactoglobulin were carried out by equilibrium dialysis, ultraviolet difference and circular dichroism techniques at 25 C. Binding isotherms at pH 5·0, 7·0 and 9·0 show cooperative binding at all concentrations of detergents and the number of avai...

In the crystal structure of the title compound, C(8)H(10)BrN(2)O(+)·Br(-), inter-molecular N-H⋯Br hydrogen bonds link the mol-ecules into infinite chains along [001]. The inclined angle between the pyridine ring plane and the plane defined by the acid amide group is 63.97 (4)°.

Substances that mimic the enzyme action of glutathione transferases (which serve in detoxification) are described. These micellar catalysts enhance the reaction rate between thiols and activated halogenated nitroarenes as well as alpha,beta-unsaturated carbonyls. The nucleophilic aromatic substitution reaction is enhanced by the following surfactants in descending order: poly(dimethyldiallylamm...

MCM-48 were prepared using hexadecyl trimethyl ammonium bromide and TEOS modified with N1-(3-trimethoxysilylpropyl) diethylenetriamine by post-synthesis method to develop efficient adsorbent for heavy metal adsorption. These materials determined X-ray diffraction, N2 adsorption–desorption measurement, scanning electron microscopy. The results show that the modification of resulted in a decrease...
