For professionals in pharmaceutical research and development, the selection of high-quality raw materials is a critical determinant of project success. Among the specialized chemicals essential for advanced therapeutic development, DOTA-NHS Ester (CAS: 170908-81-3) holds significant importance. This bifunctional chelating agent is integral to the creation of targeted imaging agents and therapeutics, making its reliable sourcing a priority. As a reputable manufacturer and supplier based in China, we aim to provide comprehensive information for R&D professionals looking to buy DOTA-NHS Ester.

DOTA-NHS Ester serves a dual purpose, acting as both a chelator for metal ions and an activated ester for conjugation. The DOTA moiety forms highly stable complexes with a wide range of clinically relevant metal ions, including radiometals used in diagnostic imaging (like 68Ga for PET scans) and targeted radionuclide therapy (like 177Lu). The N-hydroxysuccinimide (NHS) ester component readily reacts with primary amine groups on biomolecules such as proteins, peptides, and antibodies. This reaction creates a robust amide linkage, effectively attaching the DOTA chelator to the targeting molecule. This precise conjugation is key to developing molecules that can specifically target diseased cells.

The applications of DOTA-NHS Ester are diverse and impactful. In diagnostic imaging, it enables the development of highly specific PET and SPECT tracers, allowing for early and accurate detection of diseases. In theranostics, it is a foundational component for creating agents that can both diagnose and treat conditions like cancer, offering a personalized treatment approach. Furthermore, its utility extends to enhancing MRI contrast agents and facilitating various protein-labeling techniques for research. The quality and purity of the DOTA-NHS Ester are paramount for the efficacy and safety of these applications.
