| (-)-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 |
