DOTA-tris(TBE)-amido-dPEG®11-MAL, product number QBD-11166, is a thiol-reactive DOTA compound containing a medium-length (37 atoms, 44.5 Å), single molecular weight, discrete polyethylene glycol (dPEG®) spacer between the DOTA and the maleimide groups. The macrocyclic 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) moiety is protected with tert-butyl ester (TBE) groups on the four acetate units.
DOTA is a popular, effective bifunctional chelator that is used in radiopharmaceutical applications (radioimaging, radiotherapeutics) that require trivalent isotopes of yttrium or lanthanides. This form of DOTA has the four acetate groups protected with tert-butyl esters (TBE). This intermediate DOTA form is not an effective chelator, but it is useful in situations where the DOTA needs to be incorporated into the molecule at an early stage of development.
