Combined use of l-alanine tert butyl ester lactate and trimethyl-ß-cyclodextrin for the enantiomeric separations of 2-arylpropionic acids nonsteroidal anti-inflammatory drugs
(2015)In this study, a new CE method, employing a binary system of trimethyl-ß-CD (TM-ß-CD) and a chiral amino acid ester-based ionic liquid (AAIL), was developed for the chiral separation of seven 2-arylpropionic acid nonsteroidal ...
