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.

Two types of chiral analytes, the urea and amide derivatives of alpha-phenylethylamine, were prepared. The effect of inter-molecular hydrogen-bonding interaction on self-discrimination of the enantiomers of analytes has been investigated using high-resolution (1)H NMR. It was found that the urea

For biocatalytic production of pharmaceutically important chiral amines the ω-transaminase enzymes have proven useful. Engineering of these enzymes has to some extent been accomplished by rational design, but mostly by directed evolution. By use of a homology model a key

The economic and effective method for preparation of R-(-)-ibuprofen by diastereomer crystallization was developed. R-(-)-ibuprofen was resolved from racemic ibuprofen by forming R-(-)-ibuprofen-R-(+)-alpha-methylbenzylamine diastereomeric salt with R-(+)-alpha(-methylbenzylamine and crystallization. The purity of R-(-)-ibuprofen-R-(+)-alpha-methylbenzylamine diastereomeric salt was tested and confirmed using
