Hazard Information | Back Directory | [Description]
(R)-(+)-1-(1-Naphthyl)ethylamine is a reagent used in the formation of isolated acids via salt formation. It is also a raw material for the synthesis of (R)-1-(1-Naphthyl)ethyl isocyanate. In materials research, the use of Reflectance Absorption Infrared Spectroscopy (RAIRS) can be used to study the structure, bonding and orientation of R-1- nea and (S)-(-)-1-(2-naphthyl)ethylamine (S-2- nea) on Pd(1 1 1). | [Chemical Properties]
Colorless to light yellow liqui | [Uses]
(R)-(+)-1-(1-Naphthyl)ethylamine(3886-70-2) is used in chiral synthesis in organic reactions including the synthesis of β-amino acids and the enantioselective of ketones to nitroolefins.
| [Application]
Absolute configuration of primary amines determined using chiral (2-nitrophenyl)proline amides and 1H NMR. | [General Description]
(R)-(+)-1-(1-Naphthyl)ethylamine(3886-70-2) is a chiral derivatization reagent useful for all gas chromatography (GC) applications in the chiral field. It is specially selected to meet the requirements for derivatization reagents for enantiomeric excess determinations.
| [Solubility in organics]
(R)-(+)-1-(1-Naphthyl)ethylamine is soluble in chloroform and ethanol. Insoluble in water. | [Purification Methods]
Purify the amine by distillation in a good vacuum. [Mori et al. Tetrahedron 37 1343 1981, cf Wilson in Topics Stereochem (Allinger and Eliel eds) v o l 6 135 1971, Fredga et al. Acta Chem Scand 11 1609 1957.] The hydrochlorides crystallise from H2O [] D 18 ±3.9o (c 3, H2O), and the sulfates recrystallise from H2O as tetrahydrates m 230-232o. The RS-amine has b 153o/11mm, 156o/15mm, 183.5o/41mm [Blicke & Maxwell J Am Chem Soc 6 1 1780 1939]. [Beilstein 12 III 3111.] |
