COMPARISON OF 2 HPLC TECHNIQUES FOR MONITORING ENANTIOSELECTIVE REACTIONS FOR THE RESOLUTION OF (R,S)-IBUPROFEN - CHIRAL HPLC VS ACHIRAL HPLC LINKED TO AN OPTICAL-ROTATION DETECTOR
A. Ducret et al., COMPARISON OF 2 HPLC TECHNIQUES FOR MONITORING ENANTIOSELECTIVE REACTIONS FOR THE RESOLUTION OF (R,S)-IBUPROFEN - CHIRAL HPLC VS ACHIRAL HPLC LINKED TO AN OPTICAL-ROTATION DETECTOR, Biotechnology techniques, 9(8), 1995, pp. 591-596
Two approaches have been used to monitor the enantioselective esterifi
cation of (R,S)-ibuprofen with 1-dodecanol catalyzed by Novozym 435. T
he first approach involves the use of a chiral column (Chiralcel OD) c
onnected to a UV detector. The second approach involves using a C-18 r
eversed-phase column connected in series to a RI detector and to an Op
tical Rotation detector; The two methods yield the same results.
