Use of semipreparative supercritical fluid chromatography to obtain small quantities of the albendazole sulfoxide enantiomers.

The semipreparative separation of the albendazole sulfoxide enantiomers using chiral supercritical fluid chromatography is presented in this work. For this purpose, a modular SFC chromatograph was adapted to work at semipreparative scale and a Chiralpak AD (250 x 10 mm) column was used. Different injection volumes were evaluated in order to obtain high… (More)
