CAS 5913-13-3: (-)-1-Cyclohexylethylamine

(R)-(-)-1-Cyclohexylethylamine is used in the preparation of benzylidene(1-cyclohexylethyl)amine by reacting with benzaldehyde. It is also used to prepare chiral polymethacrylamides, which are employed as stationary phases for the liquid-chromatographic resolution of racemic amides. In addition to this, it is used in the preparation of polyamides bound to silica gel for high performance liquid chromatography, which are pressure-stable. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

(R)-(-)-1-Cyclohexylethylamine (CHEA) is an amine that has a linker. It is a primary amine that can form a base with a strong acid, such as hydrochloric acid. CHEA is used in the synthesis of pharmaceuticals and other organic compounds. It is synthesized from styrene and ammonia by heating at high temperatures. The synthesis of CHEA requires microwaves to activate the reaction. This chemical can be purified using high-performance liquid chromatography and then converted to the (-) form by reacting with trifluoroacetic acid in the presence of palladium complexes.
