General description

(S)-(−)-α-Methylbenzylamine is a chiral derivatizing agent, which is employed for derivatizing enantiomers into diastereoisomers.

application

(S)-(−)-α-Methylbenzylamine may be used as a chiral derivatizating reagent for the determination of acetyl-D-carnitine (D-AC) in acetyl-L-carnitine (L-AC) using high-performance liquid chromatographic (HPLC) enantioseparation method.
