Chiral counter-ions in the mobile phase enable enantiomeric separation of acids and amines. Key counter-ion properties like acid-base character and hydrophobicity are crucial for successful chiral ion-pair chromatography.

Area of Science:

  • Analytical Chemistry
  • Chromatography

Context:

  • Enantiomeric separation is critical in pharmaceuticals and chemical synthesis.
  • Chiral ion-pair chromatography (CIPAC) offers a method for resolving enantiomers.

Purpose:

  • To review the principles and variables of enantiomeric separation using chiral counter-ions.
  • To highlight the essential properties of effective chiral counter-ions for separation.

Summary:

  • Chiral counter-ions in the mobile phase facilitate the separation of enantiomers of acids and amines via chiral ion-pair chromatography.
  • Successful separation hinges on selecting counter-ions with appropriate acid-base properties, hydrophobicity, functional groups, and high enantiomeric purity.
  • The review also covers the impact of chromatographic conditions and CIPAC applications.
