Three independent mol-ecules comprise the asymmetric unit of the title compound, C10H19N5O2, (systematic name: 4-amino-N-tert-butyl-3-isopropyl-5-oxo-4,5-dihydro-1H-1,2,4-triazole-1-carboxamide) . In all three mol-ecules, the triazole ring and the carboxamide group are almost coplanar [within 4.0-5.9 (9)°], particularly because of the formation of an intra-molecular N-H⋯O hydrogen bond. On othe...

The title compound, C17H27NO2S, exhibits a distorted geometry of the aromatic ring with elongated bonds at the ipso-C atom. The S atom deviates from the aromatic ring plane by 0.393 (4) Å. Similar to this, the adjacent isopropyl groups are bent out of the aromatic ring plane by -0.125 (4) and -0.154 (4) Å. Even the distant isopropyl group in para-position to the sulfonyl moiety shows a slight d...

In the title compound, C(11)H(15)NO(3), the mean planes of the carboxamide and isopropyl groups are inclined at 109.9 (1) and 128.7 (2)°, respectively, to the mean plane of the phen-oxy group. In the crystal structure, mol-ecules are stacked along the b axis, without any π-π inter-actions. The stacked columns are linked together by inter-molecular N-H⋯O hydrogen bonds, with an N⋯O distance of 2...

Sedimentation properties of the TiO2 nanoparticles with very high specific surface area (about 180m /g) based on the BET method have been investigated in various organic solvents. The TiO2 nanocolloid in the isopropyl alcohol displayed a considerably high electrostatic repulsive force, compared to that in other solvents, with negligible coalescence between the particles. Both the backscattered ...

The title compound, C12H16Cl4, is a derivative of the natural product 1-isopropyl-4-methyl-cyclo-hexa-1,4-diene, and represents a diastereomer with two trans-fused cyclo-propane rings. Both enanti-omers are present in the non-centrosymmetric polar space group Pna21. The central cyclo-hexane ring is planar within 0.02 (1) Å. The C atoms of di-chloro-methyl-ene groups deviate from this plane by 1...

The Au(I) atom in the title compound, [Au(C(6)H(12)NOS)(C(18)H(33)P)], is coordinated within a S,P-donor set that defines a slightly distorted linear geometry [S-Au-P angle = 173.44 (5)°], with the distortion due in part to a close intra-molecular Au⋯O contact [3.023 (4) Å]. The N-bound isopropyl group is disordered over two orientations in a 0.618 (15):0.382 (15) ratio.

In this study effect of Stearamide as a corrosion inhibitor for mild steel in hydrochloric acid media was investigated employing various electrochemical techniques include potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and liner polarization resistance (LPR). In view of the fact that Stearamide is an insoluble compound in water, its inhibitive effect was examined by ...

We synthesized and study the possible trypanocidal activity of 4-isopropyl salicylaldehyde and 4-isopropyl salicylic acid, these compounds were chemical derivatives of gossypol, a drug that inhibits the growth of T. cruzi in culture. These derivatives were tested in two T. cruzi strains with different in vitro susceptibility to benznidazole and nifurtimox, used as a reference drugs. It was foun...

The title compound, C(16)H(22)N(2)O(3), was synthesized during the course of a study on (1R,2S)-norephedrine-derived 1,3,4-oxadiazinan-2-ones. The conformation adopted by the isopropyl group is pseudo-axial relative to the oxadiazinan core. The allylic strain contributes to this conformational arrangement.
