Application

Tri-tert-butyl 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate (tri BOC-DOTA) can be employed as a reactant to prepare:
  • Gadolinium ion functionalized with DOTA-LAE (lactobionic acid-ethylenediamine), which is used as a contrast agent for magnetic resonance imaging (MRI).
  • DOTA-conjugates of ursolic acid and ZD2 peptide 64Cu-DOTA conjugates.
