Description: DOTA is an azamacrocyle in which four nitrogen atoms at positions 1, 4, 7 and 10 of a twelve-membered ring are each substituted with a carboxymethyl group. It has a role as a chelator and a copper chelator. It derives from a hydride of a 1,4,7,10-tetraazacyclododecane. It is a a metal chelate in use in medical diagnostics.
