Specific sequestering agents for the actinides. 3. Polycatecholate ligands derived from 2,3-dihydroxy-5-sulfobenzoyl conjugates of diaza- and tetraazaalkanes
The invention provides macrocycles useful in chelating metal ions, particularly radionuclides, to provide metal ion complexes. The invention also provides methods of using the compounds and complexes of the invention, such as in therapeutic and diagnostic applications.
A composition of matter comprising intercalated composite particles comprising a layered host material intercalated with a metal ion sequestrant having a stability constant greater than 10
15
with iron (III), wherein said sequestrant is not an alpha amino carboxylate. It further relates to articles comprising the composite particles.
This invention relates to a composition of matter comprising a functionalized mordant polymer comprising a cationic polymer having an adsorbed metal-ion sequestrant, wherein the metal-ion sequestrant has a stability constant greater than 10
