The title compound, C(9)H(7)IN(+)·Cl(-)·2H(2)O, was obtained during the synthesis of 8-iodo-quinoline from 8-amino-quinoline using the Sandmeyer reaction. The 8-iodo-quinolinium ion is almost planar. Solvent water mol-ecules and chloride ions form a hydrogen-bonded chain along the c axis via O-H⋯Cl links. The 8-iodo-quinolinium ions, which are packed along the c axis with cationic aromatic π-π ...

Kinetic parameters (Km and kcat.) of the two major forms (A and B) and a minor form (C) of human liver N-acetylglucosamine-6-sulphate sulphatase [Freeman, Clements & Hopwood (1987) Biochem. J. 246, 347-354] were determined with a variety of substrates matching structural aspects of the physiological substrates in vivo, namely heparin, heparan sulphate and keratan sulphate. Enzyme activity is hi...

In the title compound, C(16)H(12)BrN(3)O(2)S, the dihedral angle between the planes of the almost planar (r.m.s. deviation = 0.0263 Å) quinoline group and the bromo-phenyl group is 87.4 (1)°. The torsion angle of the central S-N-N-C bridge is 144.8 (2)°. The amino group has an intra-molecular contact to the quinoline N atom. The structure is stabilized by one N-H⋯O and two C-H⋯O inter-molecular...

The purpose of the work is synthesis new organomineral composites by in situ immobilization and adsorption poly[8-methacroyloxy-quinoline] on surface vermiculite study sorption properties cations Cu(II), Pb(II) Fe(III). In poly [8-oxyquinolinemethacrylate] was carried out initiated radical polymerization 8 oxyquinoline methacrylate using 2,2′-azobisisobutyronitrile (AIBN) as a dinitrile initiat...

The title compound, C(10)H(11)N(4) (+)·Cl(-), has been synthesized by the reaction of 8-amino-quinoline and cyanamide. The dihedral angle between the plane of the guanidine group and the quinoline ring system is 68.64 (13)°. The crystal structure is stabilized by inter-molecular N-H⋯Cl hydrogen bonds.
