General description

(R)-(-)-Mandelic acid, a chiral resolving agent, is also used as a building block to synthesize pharmaceutical drugs such as penicillin and cephalosporin. It can be synthesized from (R,S)-mandelonitrile with high yield and enantioselectivity using nitrilase enzyme .

(R)-(−)-Mandelic acid is a carboxylic acid used as a starting material to synthesize antibiotics, antitumor agents, and antiobesity drugs.

Application

(R)-(-)-Mandelic acid has been used in studies to assess its ability to undergo spontaneous oscillatory chiral conversion and spontaneous condensation to form polymandelic acid.
