Description

n-Carboxymethyl)-n-(2-(Bis(Carboxymethyl)Amino)Ethyl)-3-(4-(N'-(2-((3,7,12-Trihydroxycholan-24-Oyl)Amino)Ethyl)(Thioureido)Phenyl)Alanine is a sophisticated, multifunctional chelating agent and a key intermediate in the synthesis of advanced diagnostic and therapeutic compounds. Its complex structure, featuring a bile acid derivative core linked to a polyaminocarboxylate moiety via a thiourea bridge, provides exceptional metal-binding affinity and targeted delivery capabilities. This compound is essential for researchers and manufacturers in the pharmaceutical and biotechnology sectors developing next-generation contrast agents, radiopharmaceuticals, and targeted drug delivery systems.

Application

• Pharmaceutical Intermediate: Critical building block for synthesizing gadolinium-based MRI contrast agents and other metal-chelating pharmaceuticals.
• Radiopharmaceuticals: Used as a bifunctional chelator for labeling peptides, antibodies, and other targeting vectors with diagnostic (e.g., 68Ga, 99mTc) or therapeutic (e.g., 177Lu, 90Y) radioisotopes.
• Targeted Drug Delivery: Serves as a linker molecule to conjugate cytotoxic drugs or imaging probes to bile acid transporters for hepatocyte-specific targeting.
• Research & Development: A valuable tool in academic and industrial R&D for studying liver-specific transport mechanisms and developing novel theranostic platforms.
• Specialty Chelation Chemistry: Employed in the development of high-affinity ligands for lanthanide and actinide separation processes in analytical and nuclear chemistry.
