1,4,7,10-tetraazacyclododecane (CAS: 2558-96-5), also known as cyclen, is a macrocyclic polyamine synthesized via high-dilution cyclization of diamines. It serves as a critical chelating scaffold in radiopharmaceutical development due to its strong affinity for lanthanides and actinides.
Store under inert atmosphere at controlled temperatures. Avoid inhalation of dust; use appropriate PPE including gloves and respiratory protection during handling to prevent skin irritation.
