What is Cyclen (294-90-6) used for?

Cyclen, also known as tetraazacyclododecane, is a microcyclic tetramine that can be used as a ligand to form coordination linkages with surface metal cations. It is a macrocyclic aza analogue of the crown ether 12-crown-4 and can be prepared by S-alkylation of dithiooxamide with an excess amount of bromoethane.InChI:InChI=1/C8H20N4/c1-2-10-5-6-12-8-7-11-4-3-9-1/h9-12H,1-8H2/p+4
