Features and Benefits

  • Low hydrophobicity for rapid elution of hydrophobic analytes
  • Excellent peak shape and retention of strongly basic analytes
  • Retention of polar analytes
  • Unique selectivity
  • Significantly less retention than C18 (typically requires lower % organic mobile phase)
  • Stable, low-bleed LC-MS separations
  • Compatible with highly aqueous organic phases

Two classes of molecules were designed and synthesized based on a 6-CH(3) cyclopenta[d]pyrimidine scaffold and a pyrrolo[2,3-d]pyrimidine scaffold. The pyrrolo[2,3-d]pyrimidines were synthesized by reacting ethyl 2-cyano-4,4-diethoxybutanoate and acetamidine, which in turn was chlorinated and reacted with the appropriate anilines to
