Descrizione generale

(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.

Applicazioni

(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.
