| | DL-alpha-Methylbenzylamine Usage And Synthesis |
| Chemical Properties | liquid | | Uses | Used for synthesis and as an emulsifying agent; used as a resolving agent and chiral intermediate. | | Uses | α-Methylbenzylamine can be used as a reactant for the synthesis of dihydro-5H-dibenz[c,e]azepinium salts by reacting with racemic biphenol derivatives. | | Definition | ChEBI: A phenylethylamine that is ethylamine substituted by a phenyl group at position 1. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 49, p. 4272, 1984 DOI: 10.1021/jo00196a031

Tetrahedron Letters, 27, p. 3957, 1986 DOI: 10.1016/S0040-4039(00)84883-2 | | General Description | α-Methylbenzylamine is a nitrogen source that is widely used as a representative substrate to study the chemo-enzymatic kinetic resolution of primary amines. | | 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].
