HAZARD WARNING TO USERS The procedures on the orgsyn.org website are intended for use only by persons with prior training in the field of organic chemistry. In the checking and editing of these procedures, every effort has been made to identify potentially hazardous steps and to eliminate as much as possible the handling of potentially dangerous materials; safety precautions have been inserted ...
The title compound, C17H16Br2O3, which is a restricted commercial acaricide (common name bromo-propyl-ate), has two independent and conformationally similar mol-ecules in the asymmetric unit [dihedral angles between the planes of the two phenyl rings = 68.7 (4) and 77.4 (5)°]. The C atoms of the isopropyl group of one of the mol-ecules are disordered over two sites with occupancies of 0.638 (16...
The title compound, C(12)H(16)O(5), is a derivative of β-(3,4-dihydroxy-phen-yl)-α-hydr-oxy acid. The crystal packing is stabilized by inter-molecular O-H⋯O hydrogen bonds.
The mol-ecular structure of the title compound, C(8)H(12)N(2)O, indicates that 2-isopropyl-6-methyl-pyrimidin-4-ol (the enol-form) undergoes an enol-to-keto tautomerism during the crystallization process. The pyrimidin-4(3H)-one group is essentially planar, with a maximum deviation of 0.081 (1) Å for the O atom. In the crystal structure, symmetry-related mol-ecules are linked into centrosymmeti...
In the title compound, C(11)H(14)ClNO, the herbicide propachlor, there are significant differences between the three N-C bond lengths [N-C(carbon-yl) = 1.354 (3) Å, N-C(phen-yl) = 1.444 (2) Å and N-C(isoprop-yl) = 1.496 (3) Å], indicating the presence of π delocalization involving the carbonyl group. The N atom lies 0.074 (2) Å from the plane defined by the the three bonded C atoms.
In the title compound, C(11)H(14)N(2)O(3), the bond lengths and angles are within normal ranges. Weak inter-molecular N-H⋯O inter-actions link the mol-ecules into chains along the a axis. A non-classical intra-molecular C-H⋯O inter-action (nitro O atom and a H atom of the nearest methyl group) is found, forming a six-membered ring with a twisted conformation. This six-membered ring has a twiste...
Ondansetron HCl delivery through oral route suffers due to its low bioavailability due to first-pass metabolism. Therefore, the microemulsion-based transdermal delivery may be a better substitute for it. The pseudoternary phase diagrams were constructed to determine compositions of microemulsions, and ondansetron HCl microemulsions for transdermal delivery were developed using isopropyl myrista...
Reaction of isopropyl[(2-pyridyl)alkyl]amines such as N-isopropyl-N-2-methylpyridine or N-isopropyl-N-2-ethylpyridine with aqueous solutions of NaAuCl(4) led to the formation of [LAuCl(2)][AuCl(4)] in low yields, where L = pyridyl amine bound to gold in a bidentate fashion. Reaction of 2-(3,5-diphenyl-1H-pyrrol-2-yl)pyridine with aqueous NaAuCl(4), however, proceeded with formal loss of HCl and...
