Pindolol is a non-selective beta-blocker used for treatment of hypertension and angina pectoris. It is applied as a racemate, although only the (S)-form is the active stereoisomer.

YMC offers immobilized chiral phases that can be used either in normal or reversed phase mode as well as in supercritical fluid chromatography (SFC) mode. CHIRAL ART Cellulose-SC is a very versatile phase to separate many chiral substances. YMC have developed two isocratic applications to separate the pindolol enantiomers in normal phase or reversed phase mode. Both methods offer a high resolution. The normal phase application provides more potential for a preparative scale up, while the reversed phase approach separates the enantiomers in a shorter time.
