3.5. Separation. of. stereoisomers: resolution. of. racemic. mixtures. A number of
compounds exist as racemic mixtures (i), Le. a mixture of equal amounts of two
enantiomers, (—) and (+). Often, one enantiomer shows medicinal properties.
Satyajit Sarker, Lutfun Nahar, 2013
A large number of chiral drugs, however, are sold as racemic mixtures. The
popular analgesic ibuprofen (the active ingredient in Motrin and many other
nonaspirin analgesics) is an example of a drug sold as a racemic mixture. For
racemic ...

... polarized light. Such a 50 : 50 mixture of enantiomers is optically inactive and
is referred to as a racemic mixture, a racemic modification, or simply a racemate.
By definition, a racemic mixture is optically inactive, and its rotation is always 0°.

Chirality in Drug Design and Development
Crystal Properties of Enantiomers and Racemic Compounds Statistically. 90-95%
of racemic species exist as racemic compounds while only 5-10% of racemic
species are conglomerates. These relative frequencies imply that the racemic ...

At some stage, therefore, it might be necessary to have the means of separating
individual enantiomers from a racemic mixture. This is termed resolution.Thetra-
ditional method has been to convert enantiomers into diastereoisomers, because

Handbook of Polymer Synthesis: Second Edition
If the pseudochiral centers are enantiomeric, the diad is called racemic. A
polymer containing only meso diads is called isotactic, while a polymer
consisting of racemic diads only is named syndiotactic. Polypropene in which
meso and racemic ...

pseudoracemate or a solid solution.7,8 Accordingly, a racemic mixed crystal
refers to the crystal with a random alignment of the two enantiomers in the
defined positions to give both racemic and nonracemic crystals with a variety of
ee values ...
5.2.7 The Racemic Modification A mixture of equimolecular amounts of a pair of
enantiomers is known as racemic modification. A racemic modification will be
optically inactive, because the rotation caused by one half of the mixture is
exactly ...

(4) In racemic modifications, the optical inactivity is due to cancellation of rotation
caused by two molecules which are mirror images of each other. It is due to the
external compensation. (5) Optically inactive racemic modifications can be ...
