An alternative to Synthesis of desired optical isomer is Chiral Resolution

Separation methods of racemic compounds into their 

Resolution by crystallisation
First achieved by Louis Pasteur (discovered the concept of optical 
activity). Here racemic mixture will crystalise as enantiopure
compounds after saturation in Sodium Ammonium T artrate


Chiral resolving agents

T o the racemic mixture
optically pure reagents
are added.Diesteromers
are formed often as
salts, which can be

include tartaric acid and
