Used as a chiral building block in the synthesis of pharmaceuticals and biologically active compounds. Its rigid cyclopentane backbone and two adjacent amine groups make it valuable in asymmetric synthesis and catalyst design. Commonly employed in the development of chiral ligands and organocatalysts for enantioselective reactions. Also utilized in medicinal chemistry for constructing peptidomimetics and nitrogen-containing heterocycles. The dihydrochloride salt form enhances stability and solubility, facilitating handling and use in aqueous or polar organic solvents.
