Cyclen (Standard)	Reference Standards	Others
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 ⁺/Mg ²⁺ 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 .
