General description

(R)-(+)-α-Methylbenzylamine is a high quality, useful chiral derivatization reagent for all analytical applications, specific to GC in the chiral field. It is specially selected to meet the requirements for derivatization reagents for enantiomeric excess determinations.

Application

(R)-(+)-a-Methylbenzylamine also known as (R)-(+)-1-Phenylethylamine may be used in resolution of a chiral arylalkylamine involving high-conversion enantioselective condensation with capric acid followed by hydrolysis to yield corresponding (R)-(+)-amide.

Other Notes

Chiral amine used for the determination of the enantiomeric purity of acids

A three-component chiral derivatization protocol for determining the enantiopurity of chiral diols by (1)H NMR spectroscopic analysis is described here. The present approach involves the derivatization of 1,2- 1,3- and 1,4-diols with 2-formylphenylboronic acid and enantiopure alpha-methylbenzylamine. This method affords
