(R)-Cyclohex-3-enylamine hydrochloride

This intermediate is based on a cyclohexene skeleton with a carbon-carbon double bond at the 3-position of the ring. The 1-position carbon atom acts as the chiral center, linked to a protonated amino group (-NH₃⁺Cl⁻). The fixed (R)-configuration endows it with a unique spatial structure, which can accurately meet the configuration requirements of downstream synthesis. Compared with free amine, its hydrochloride form has higher stability with resistance to oxidation, and good solubility in polar solvents such as water, methanol and ethanol. It can significantly simplify feeding, reaction and post-treatment operations in the synthesis process, improving process compatibility.

In terms of applications, first, as a core intermediate for chiral active pharmaceutical ingredient (API) synthesis, it is widely used in the R&D and production of nervous system drugs, anti-infective drugs and other categories. The (R)-configuration directly determines the binding efficiency between drugs and targets, ensuring efficacy exertion and reducing side effects caused by non-target configurations. Second, it can be used as a precursor for preparing chiral amine ligands, matching transition metal catalysts to participate in asymmetric hydrogenation, addition and other reactions, greatly improving the chiral selectivity and purity of downstream products.

For industrial application, this intermediate has strict purity requirements, generally requiring chiral purity (ee value) ≥ 98%. For storage, it should be sealed and placed in a dry, cool and well-ventilated environment to avoid moisture absorption, caking or degradation, so as to maintain the stability of product quality.
