Furthermore, most formulations of chiral pesticides are composed of
racemic mixtures, and it is, therefore, essential to define their stereoselectivity patterns to better estimate risk assessment.
All chemicals shown in Table 2 were purchased from Cayman Chemicals (Michigan, USA) and were provided as
racemic mixtures for individual cathinones (99% purity).
In these latter two cases, the effect of separating the
racemic mixture into enantiomers is "unexpected" in the sense that we could not have known in advance that there would be such a multiplier effect in this particular case.
D-Phe imprinted P(AA-co-AN) membrane prepared by the wet phase inversion method can be successfully used for chiral resolution of the DL-Phe
racemic mixture. Morphological studies revealed that the membrane was very thin and the pore diameter was in nanometers.
It is also available as
racemic mixture. Favorable pharmacokinetic profile of KTP in humans made it a suitable and effective NSAID for veterinary use.
This allows selective chemistry, for example, regio-selectively transforming a single functionality (out of several) in a single molecule or, more importantly, effecting the biotransformation of one isomer in a
racemic mixture, facilitating its separation into the component isomers.
The
racemic mixture of the antioxidant alpha-lipoic acid (ALA) enhances insulin-stimulated glucose metabolism in insulin-resistant humans and animals.
Tramadol is a
racemic mixture consisting of two enantiomers ([+] tramadol and [-] tramadol).
(114) An equal mixture of enantiomers is termed a
racemic mixture. (115)
Lima (2001) found that traps baited with a
racemic mixture of 5,9-dimethylpentadecane captured more males than traps baited with pure stereoisomers.
group P (pre-treatment) patients received a
racemic mixture of ketamine 10 mg in 0.9% N/S 1.0 ml, followed by an infusion of propofol.
