This samarium(III) complex with a chiral diaminopropane tetraacetate ligand is primarily utilized in research settings for biomedical applications. It is explored as a potential contrast agent in magnetic resonance imaging (MRI), where lanthanide complexes can alter the relaxation properties of water protons to enhance image contrast for diagnosing soft tissue abnormalities, such as in the brain and spine. Additionally, it is studied for the behavior of lanthanide chelates in biological systems and potential roles in targeted therapies.
