Kilty ran the first leg of that relay race to give his team a flying start and is likely to do so again in the final next week with racemates Zharnel Hughes, Adam Gemili and Harry Aikines-Aryeetey.
However, the literature limitation of the pharmacological data for the new cathinone derivatives racemates lets researchers assume that the case for most phenylalkylamine compounds will be similar to methcathinone.
(38) When the mixture of enantiomers is fifty-fifty, it is known as a "racemic" mixture, and the separation into enantiomers or "racemates" is sometimes called a "chiral switch." (39)

The results obtained thus demonstrate the usefulness of resolution of racemates and enantiomerically enriched compounds in drug development of antimicrobial agents of coordinated compounds.
When we obtained the one-handed helical PTrMA, we did not expect a high chiral recognition ability of the PTrMA, because the polymer is almost entirely surrounded by nonpolar triphenylmethyl groups, which cannot strongly interact with many racemates. However, when we checked its chiral recognition ability by a simple experiment, we immediately noticed its high ability, and wanted to use the polymer as the CSP for HPLC.

The optical resolution of racemates has been essential in the perfume production pharmaceutical industry food preparation and so forth due to the harmful effect of one of the enantiomer of racemate mixture.
They also discuss the methodologies for determination of the stereoisometric composition of chiral compounds and chiral separation, such as gas and liquid chromatography on chiral stationary phases, capillary electrophoresis, and nuclear magnetic resonance spectroscopy; methodologies for the determination of absolute configuration, such as X-ray analysis, nuclear magnetic resonance, and chiroptical methods; and methodologies for the resolution of racemates, such as crystallization, preparative chromatography, and kinetic resolution.
