2-Nitro-p-phenylene dibenzenesulfonate
In the title compound, C(18)H(13)NO(8)S(2), the nitro-phenyl ring forms dihedral angles of 46.67 (7) and 75.40 (6)° with the phenyl rings. The nitro group makes a dihedral angle of 26.13 (8)° with the attached ring. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کاملSynthesis and characterization of nitro-p-xylenes.
In this paper we elected to nitrate p-xylene because this compound has only one mononitro- and trinitro- isomer. Trinitro-p-xylene was used as a starting material for the synthesis of other compounds in subsequent work. The mononitration of p-xylene can be easily carried out at 30 degrees C. Nitro-p-xylene is easily nitrated to dinitro-p-xylene at a temperature of 80 degrees C. The trinitro-p-x...
متن کامل2-Nitro-p-phenylene bis(toluenesulfonate)
In the mol-ecule of the title compound, C(20)H(17)NO(8)S(2), the two toluene rings are oriented at a dihedral angle of 3.65 (4)°, while the nitrophenyl ring is oriented at dihedral angles of 44.39 (3) and 47.44 (3)° with respect to the toluene rings. An intra-molecular C-H⋯O hydrogen bond results in the formation of a five-membered ring, which adopts an envelope conformation. In the crystal str...
متن کاملBioassay of 2-nitro-p-phenylenediamine for possible carcinogenicity.
A bioassay for the possible carcinogenicity of 2-nitro-p-phenylenediamine was conducted using Fischer 344 rats and B6C3F1 mice. 2-Nitro-p-phenylenediamine was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. Twenty animals of each sex and species were placed on test as controls. The high and low dietary concentrations of 2-ni...
متن کاملBioassay of 3-nitro-p-acetophenetide for possible carcinogenicity.
A bioassay for possible carcinogenicity of 3-nitro-p-acetophenetide was conducted using Fischer 344 rats and B6C3F1 mice. 3-Nitro-p-acetophenetide was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species, with the exception of low dose male mice, of which there were 49. Fifty animals of each sex and species were placed on test as ...
