1. Chronic renal failure was induced in rats by surgical removal of thirteen-sixteenths of renal tissue. 2. The metabolism of p-amino[14C]benzoic acid was studied in the isolated perfused livers of control and chronically uraemic rats. There was a slower rate of clearance and decreased overall metabolism of the compounds in the uraemic rats. 3. Conjugation of p-amino[14C]benzoic acid with glyci...

In the title compound, C(14)H(13)NO(4)S, the dihedral angle between the aromatic rings is 35.47 (10)°. In the crystal, adjacent mol-ecules are connected by pairs of O-H⋯O hydrogen bonds, forming head-to-head centrosymmetric dimers typical for carb-oxy-lic acids. Adjacent dimers are further linked through C-H⋯O inter-actions on one side and N-H⋯O inter-actions on the other, generating [010] chains.

In the title compound, C(10)H(11)NO(4)·H(2)O, the carboxyl group is twisted at a dihedral angle of 6.1 (3)° with respect to the benzene ring. In the crystal, the organic mol-ecules are linked by pairs of O-H⋯O hydrogen bonds involving both carboxyl groups, forming zigzag chains propagating along the b-axis direction. The water mol-ecules form [100] chains linked by O-H⋯O hydrogen bonds. The org...

the ultrasonic velocity, density and viscosity of some schiff bases of 4-amino benzoic acid  were measured in 1,4-dioxane and dimethylformamide at 308.15 k. various acoustical properties such as isentropic compressibility (ks), rao’s molar sound function (rm), the van der waals constant (b), molar compressibility (w), inter molecular free length (lf), relaxation strength (r), internal pressure ...

In this research the polymer which contains aldehyde group [H1] has been prepared by oxidation [H] using oxidizing agent (Dess Martin Periodinane), dialyzed ethanol, Schiff bases[H2,H5andH8] compounds have through reaction of compound with appropriate amines, [H3] hydroquinazolin ring [H2] 2-amino benzoic acid.[H4]which cyclization phthalic anhydride. [H6,H7]were [H5] acid and anhydriede. React...
