2,4-Dinitrophenyl 4-toluenesulfonate: molecular aggregation through weak C—H...O interactions

“…Comment p-Toluenesulfonates are used in monitoring the merging of lipids (Yachi et al, 1989), studying membrane fusion during acrosome reaction (Spungin et al, 1992), the development of immunoaf®nity chromatography for the puri®cation of the human coagulation factor (Tharakan et al, 1992), chemical studies on viruses (Alford et al, 1991), the development of technology for linking photosensitizers to model monoclonal antibodies (Jiang et al, 1990) and the chemical modi®cation of sigma subunits of the E. coli RNA polymerase (Narayanan & Krakow, 1983). The crystal and molecular structure determination of the title compound, (I), was undertaken because of the biological importance of its analogues.…”

1H-1,2,4-Triazol-4-ium 4-nitrobenzenesulfonate monohydrate

“…For details and applications of aromatic sulfonates, see: Yachi et al (1989); Spungin et al (1992); Jiang et al (1990); Narayanan & Krakow (1983).…”

“…In recent years, there has been of great interest in the design and utilization of 1,2,4-triazole and its derivatives in coordination and biological chemistry for they represent the simple small molecular ligands. Aromatic sulfonates are used in monitoring the merging of lipids (Yachi et al, 1989) and in many other fields (Spungin et al, 1992;Jiang et al, 1990;Narayanan & Krakow, 1983). An X-ray study of the title compound was undertaken in order to determine its crystal and molecular structure owing to the biological importance of its analogues.…”

Layer architecture in 4-nitrophenyl and 4-chlorophenyl 3-nitrobenzenesulfonate at 100 K

“…Aromatic sulfonates are used in detecting speci®c organic anion-binding proteins in the liver plasma membrane (Yachi et al, 1989) and in many other ®elds (Spungin et al, 1992;Tharakan et al, 1992;Alford et al, 1991;Jiang et al, 1990;Narayanan & Krakow, 1983). The present X-ray study of compounds (I) and (II) was undertaken in order to determine their crystal and molecular structures.…”
