1,4,7,10-Tetraazacyclododecane-1,4,7-triacetic acid sodium salt is a macrocyclic chelating agent derived from DOTA. It serves as a critical precursor for radiopharmaceuticals, featuring high stability constants with lanthanides and actinides. The compound is synthesized via cyclization of 1,4,7,10-tetraazacyclododecane followed by acetylation and neutralization. Molecular Formula: C12H20N4NaO6. CAS No.: 15833-97-7.
Store in a dry, inert atmosphere below 25°C to prevent hydrolysis. Handle with PPE; avoid inhalation of dust. Clinical use requires strict regulatory compliance regarding radioisotope purity and sterility.
