The enantiomers of three chiral compounds of neural interest, N-(2-heptyl)propargylamine (2-HPA), 2-heptylamine (2-HA) and 2-HPPA were separated analytically using capillary electrophoresis (CE) with cyclodextrin chiral selectors. And dansyl chloride was chosen as the reagent for pre-column derivation to give 2-HPA derivatives. The effects of pH, beta-CD concentration, electrolyte concentration and...
HPLC was used to separate chiral compounds with chiral column. Another method was used in HPLC with chiral mobile phase additives to separate chiral compounds. Using chiral mobile phase additives is a good way to separate the chiral compounds. The structure of the derivative takes an important role in separation. We derivatized 2-heptamine with benzene sulfonyl chloride and dansyl chloride, Using...
Purpose. This study was to develop and validate a new chiral HPLC-UV method for the quantitative analysis of enantiomeric ritalinic acid (RA) in human plasma. Methods. An α1-acid glycoprotein column was used with the mobile phase containing 0.4% acetic acid and 0.1% dimethyloctylamine, pH 3.4. The detection of enantiomeric RAs was at 220 nm. Results. A baseline separation for d- and l-RA was...
