Biological Activity: Cyclen is a macrocyclic tetraamine chelating agent. Cyclen is the aza analogue of crown ether, used as a precursor for MRI contrast agents, and is an intermediate for the preparation of effective macrocyclic chelates. Cyclen is employed as a structural regulator through interfacial polymerization of polyethleneimine (PEI) and trimesoyl chloride (TMC) to develop polyamide NF membrane with efficient Li+/Mg2+ separation performance. Cyclen has specific cavity structure and exhibits selective coordination properties for Li+ ions[1][2].

Cyclen (Standard) | ≥98% | Cyclen (Standard) is the analytical standard substance of Cyclen. This product is used for research and analytical applications. Cyclen is a macrocyclic tetrathiolate chelating agent. Cyclen is a nitrogen-containing analogue of crown ethers and can be used as a precursor for MRI contrast agents, as well as an intermediate for preparing highly efficient macrocyclic chelates. As a structural regulator, Cyclen can be prepared into polyamide nanofiltration membranes with efficient Li+/Mg2+ separation performance through the interfacial polymerization of polyethyleneimine (PEI) and meta-benzotriazole chloride (TMC). Cyclen has a unique cavity structure and exhibits selective coordination properties for Li+ ions. | ||||||||||||||||||||
