General description

2-Chloromandelic acid (2-ClMA) is a mandelic acid derivative. A report based on its solid state-NMR, X-ray powder diffraction (XPRD) and Fourier transform infrared spectroscopy (FTIR) data reveals that in solid state 2-ClMA exists as a racemic compound. The study also suggests that the crystals of racemic 2-ClMA belongs the monoclinic space group P21/c. The efficiency of (R)-(+)-N-benzyl-1-phenylethylamine in resolving racemate 2-ClMA has been investigated.

During the resolution of 2-chloromandelic acid with (R)-(+)-N-benzyl-1-phenylethylamine, the crystals of the less soluble salt were grown, and their structure were determined and presented. The chiral discrimination mechanism was investigated by examining the weak intermolecular interactions (such as hydrogen bond...

Optically pure 2-chloromandelic acid (ClMA) is a very important chiral drug intermediate for synthesis of (S)-clopidogrel, belonging to the platelet aggregation inhibitor. Enantioselective resolution of (R,S)-2-chloromandelic acid was carried out in organic solvent through irreversible transesterification catalyzed by lipase AK...

The chromatographic retention mechanism describing relationship between retention factor and concentration of Cu(2+) (l-phenylalanine)2 using chiral ligand mobile phase was investigated and eight mandelic acid derivatives were enantioseparated by chiral ligand exchange chromatography. The relationship between retention factor and concentration...
