Bioassay of 1-phenyl-3-methyl-5-pyrazolone for possible carcinogenicity.
A bioassay of 1-phenyl-3-methyl-5-pyrazolone for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. 1-Phenyl-3-methyl-5-pyrazolone was administered in the feed, at either of two concentrations, to groups of 49 or 50 male and 50 female animals of each species. The high and low concentrations of 1-phenyl-3-methyl-5-pyrazolone utilized were, respectively, 5,000 and 2,50...
متن کاملSynergistic Solvent Extraction of Trivalent Lanthanoids with Mixtures of 1-Phenyl-3-methyl-4-benzoyl-5- pyrazolone and Crown Ethers
The synergistic solvent extraction of 14 trivalent lanthanoids (except Pm) with 1-phenyl-3-methyl-4-benzoyl-5pyrazolone(HP) and dibenzo-18-crown-6 (DB18C6) or dibenzo-24-crown-8(DB24C8) in 1, 2-dichloroethane has been studied. It was found that in the presence of HP alone the lanthanoids have been extracted as LnP3∙HP and in the presence of mixtures of HP and crown ethers (S) − as LnP3∙S. On th...
متن کامل4-(3-Methyl-5-phenyl-1H-pyrazol-1-yl)benzenesulfonamide
With respect to the planar five-membered ring of the title compound, C(16)H(15)N(3)O(2)S, the phenyl ring is aligned at 47.0 (1)° and the phenyl-ene ring at 37.6 (1)°. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the pyrazole N atom of another mol-ecule, resulting in the formation of a layer parallel to...
متن کامل3-Methyl-5-phenoxy-1-phenyl-1H-pyrazole-4-carbaldehyde
In the title compound, C(17)H(14)N(2)O(2), the pyrazole ring makes dihedral angles of 73.67 (4) and 45.99 (4)°, respectively, with the adjacent phenyl and phen-oxy rings. In the crystal, there are no classical hydrogen bonds, but a weak C-H⋯π inter-action is observed.
متن کامل4-[(3-Hydroxyanilino)(phenyl)methylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
In the title compound, C(23)H(19)N(3)O(2), the dihedral angles formed by the pyrazolone ring with the three benzene rings are 30.91 (6), 60.96 (4) and 57.01 (4)°. The ligand is in the enamine-keto form and its structure is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, O-H⋯N hydrogen bonds link mol-ecules into chains parallel to [01-1].
