(-)-O-ACETYL-D-MANDELIC ACID Usage And Synthesis

Chemical Properties	white to light yellow crystal powde
Uses	The (R)- and (S)-isomers are chiral derivatizing agents for NMR determination of enantiomeric purity of α-deuterated carboxylic acids, alcohols, and amines.
Uses	(R)-(-)-O-Acetylmandelic acid may be used as a precursor to prepare a chiral diamine, which is an intermediate to prepare Utenone A. It may also be used to prepare ethyl (2′R)-2′-acetoxy-2′-phenylethanoate.
General Description	(R)-(-)-O-Acetylmandelic acid is a chiral derivatizing agent for NMR determination of enantiomeric purity of α-deuterated carboxylic acids, alcohols, and amines.
Purification Methods	It crystallises from H2Owith 1mol of solvent which is removed on drying, or from other solvents as for the S-iso
