 Diastereomeric recrystallization

Diastereomeric recrystallization is a technique used in organic chemistry to separate diastereomers, which are types of stereoisomers. Unlike enantiomers, which are non-superimposable mirror images of each other and have identical physical properties except for their interactions with plane-polarized light, diastereomers have different physical properties due to their non-mirror-image relationships.
