Description

(5R,6S)-2,2-Dimethyl-6-(1,4,7,10-Tetraazacyclododec-1-Yl)-1,3-Dioxepan-5-Ol is a sophisticated bifunctional chelating agent that combines a protected sugar-like moiety with a macrocyclic tetraazacyclododecane (cyclen) ring system. This molecular architecture is critical for creating stable, targeted complexes with metal ions, particularly lanthanides and transition metals, for advanced diagnostic and therapeutic applications. It is an essential high-purity intermediate for research institutions and pharmaceutical developers working on next-generation contrast agents and radiopharmaceuticals.

Application

• Contrast Agent Precursor: Serves as a key building block for synthesizing gadolinium(III)-based MRI contrast agents, where the cyclen ring provides exceptional kinetic and thermodynamic stability.
• Radiopharmaceutical Development: Used in the chelation of radioisotopes like copper-64, gallium-68, and lutetium-177 for Positron Emission Tomography (PET) imaging and targeted radionuclide therapy.
• Bifunctional Chelator (BFC): The hydroxyl group on the dioxepane ring allows for further conjugation to targeting vectors (e.g., antibodies, peptides, small molecules), enabling the creation of tumor-specific imaging and therapeutic probes.
• Chemical Biology Research: Employed in the development of metal-based sensors and probes for studying biological processes in vitro and in vivo.
• Material Science: Can be utilized to functionalize surfaces or nanoparticles with metal-chelating properties for catalysis or sensing applications.
