The asymmetric unit of the title compound, C(15)H(10)BrClO(3), consists of three crystallographically independent mol-ecules. The dihedral angles between the benzene rings in the three mol-ecules are 68.8 (2), 0.7 (3) and 66.1 (2)°. In the crystal, the three independent mol-ecules are inter-connected by C-H⋯O hydrogen bonds, leading to isolated trimers.

The asymmetric unit of the title compound, C(15)H(10)Br(2)O(3), consists of three crystallographically independent mol-ecules (A, B and C). The phenyl rings in mol-ecules A, B and C make dihedral angles of 6.1 (3), 3.2 (2) and 54.6 (2)° to each other, respectively. In the crystal, mol-ecules are linked into two-dimensional layers parallel to the ab plane by inter-molecular C-H⋯O hydrogen bonds....

This chapter reviews the occurrence, distribution, metabolism, transport, and actions of the simple sulphur‐containing nonproteinaceous amino acid taurine. It is a ubiquitous constituent of virtually all animal cells, particularly enriched in the electrically excitable cells of the nervous system, retina, heart, and muscles. Taurine is present in both neuronal and glial cells, exhibiting modera...

In the title compound, C(15)H(11)BrO(4), the dihedral angle between the aromatic rings is 66.77 (8)°. In the crystal, O-H⋯O, C-H⋯Br and C-H⋯O hydrogen bonds link the mol-ecules, forming layers lying parallel to (101). The crystal packing is further consolidated by C-H⋯π inter-actions and π-π stacking inter-actions [centroid-centroid distance = 3.5476 (7) Å].

The title compound, C(15)H(11)ClO(4), consists of a chloro-benzene ring and a phenol ring which are linked together by a 1,4-dioxo-2-oxabutane-1,4-diyl group. The dihedral angle between the chloro-benzene and phenol rings is 65.70 (11)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains along [010].

In the title compound, C(16)H(13)BrO(4), the benzene rings are almost perpendicular to each other, making a dihedral angle of 84.07 (8)°. In the crystal, the mol-ecules are linked into chains along the a axis via inter-molecular C-H⋯O hydrogen bonds. A C-H⋯π inter-action is also observed.

In the title compound, C(16)H(13)ClO(3), the dihedral angle between the benzene rings is 80.74 (8)°. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules to form C(11) chains propagating in [010].

The title compound, C(16)H(13)BrO(3), consists of a toluene ring and a bromo-benzene ring which are linked together by a 2-oxopropyl acetate group. The dihedral angle formed between the toluene and bromo-benzene rings is 80.70 (7)°. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

conclusions according to achieved results, it was defined that swcnts is a quite effective adsorbent in removal of 2, 4-d from aqueous environments. results maximum adsorption capacity of the swcnts was 979.6 mg/g at ph5, contact time 45 min, initial concentration of 5000 µg/l, and 23 ± 2 ◦c temperatures, when 97.96% of 2, 4-d herbicide were removed. the adsorption equilibriums were analyzed by...
