설명

일반 설명

(R)-(-)-O-Acetylmandelic acid is a chiral derivatizing agent for NMR determination of enantiomeric purity of α-deuterated carboxylic acids, alcohols, and amines.

애플리케이션

(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.
