Used primarily as a building block in organic synthesis, especially in the production of pharmaceuticals and agrochemicals. It serves as a diamine linker in the preparation of polymeric materials and crosslinking agents. Due to its primary amine groups and defined chain length with a central double bond, it is employed in the development of specialty chemicals requiring rigid spacers or reactive handles. Also utilized in the synthesis of chelating agents and functionalized polymers where controlled geometry and reactivity are important. Its hydrochloride salt form enhances stability and solubility, facilitating handling in aqueous or polar environments during synthetic processes.
