"In the ?-CH 3 series, one of the optical isomers of each enantiomorphic pair is about twice as active as the racemic mixture; the other isomer is devoid of significant analgesic activity ."

This racemic mixture can be separated into its optical isomers : { { # tag : ref | Enantiomers are molecules that are mirror images of one another; they are structurally identical, but of the opposite orientation.
33.
Werner also prepared complexes with optical isomers, and in 1914 he reported the first synthetic chiral compound lacking carbon, known as hexol with formula [ Co ( Co ( NH 3 ) 4 ( OH ) 2 ) 3 ] Br 6.

Using chelating ethylenediamine ligands in place of ammonia gives tris ( ethylenediamine ) cobalt ( III ) chloride ( [ Co ( en ) 3 ] Cl 3 ), which was one of the first coordination complexes to be resolved into optical isomers.
35.
One study found that, " stimulus properties of racemic cis, racemic trans, and all four individual optical isomers of 4-methylaminorex were examined in rats trained to discriminate 1 mg / kg of S ( + ) amphetamine sulfate from saline.
36.
The CAS number of glyceraldehyde 3-phosphate is 591-59-3 and that of D-glyceraldehyde 3-phosphate ( one of the two optical isomers of the compound and the one most often occurring in living organisms ) is 591-57-1.
37.
His theory allows one to understand the difference between a coordinated ligand and a charge balancing ion in a compound, for example the chloride ion in the cobaltammine chlorides and to explain many of the previously inexplicable isomers . 162x162pxIn 1914, Werner first resolved the coordination complex, called hexol, into optical isomers, overthrowing the theory that only carbon compounds could possess chirality.
