The Uses of (R)-(+)-1-Phenylethylamine
(R)-(+)-1-Phenylethylamine is a chiral amine used for the determination of the enantiomeric purity of acids.
The Uses of (R)-(+)-1-Phenylethylamine
(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.
Definition
ChEBI: The (R)-enantiomer of 1-phenylethanamine.
General Description
(R)-(+)-α-Methylbenzylamine is a chiral amine.
Flammability and Explosibility
Non flammable
Purification Methods
Dissolve the amine in toluene, dry over NaOH and distil; fraction boiling at 187-188o/atm is collected. Store it under N2 to avoid forming the carbamate and urea. Similarly for the S-(-) enantiomer [2627-86-3]. [Ingersoll Org Synth Coll Vol II 503 1943, Robinson & Snyder Org Synth Coll Vol III 717 1955, Beilstein 12 IV 2424, 2425.]
