http://www.chem.ucla.edu/~harding/IGOC/R/racemize.html WebDefinition. Racemization is a process wherein optically active compounds (which consist of only one enantiomer) are converted into an equal mixture of enantiomers with zero optical activity (a racemic mixture). Racemization rates are dependent on the molecule and conditions such as pH and temperature.

Thalidomide is racemic; while S-thalidomide is the bioactive form of the molecule, the individual enantiomers can racemize to each other due to the acidic hydrogen at the chiral centre, which is the carbon of the glutarimide ring bonded to the phthalimide substituent. The racemization process can occur in vivo. The process of conversion of one enantiomer to its mirror-image versio…
