Description

Lutetium-176 is a stable, non-radioactive isotope of the rare earth element Lutetium, with the CAS registry number 14452-47-2. This high-purity isotope is a critical precursor material for the production of the medical radioisotope Lutetium-177 via neutron activation. It is essential for industries requiring a reliable and high-quality source material for targeted radionuclide therapy and advanced nuclear research.

Application

• Medical Radioisotope Production: Primary target material for neutron irradiation to produce the therapeutic isotope Lutetium-177 (Lu-177), used in cancer treatments like prostate cancer therapy (PSMA-targeted).
• Nuclear Medicine Research: Serves as a starting material in research and development of new radiopharmaceuticals and therapeutic agents.
• Neutron Activation Analysis: Used as a flux monitor or target in neutron activation processes within research reactors.
• Isotopic Tracer Studies: Employed in geological, environmental, and material science research as a stable isotopic tracer.
• High-Purity Material Standards: Utilized in the calibration of analytical instruments and the creation of certified reference materials.

Quality Control

Our Lutetium-176 is produced and handled under stringent quality management systems to ensure isotopic purity and chemical consistency suitable for medical and research applications. Each batch is analyzed for isotopic abundance and elemental impurities using advanced techniques like Inductively Coupled Plasma Mass Spectrometry (ICP-MS). A comprehensive Certificate of Analysis (COA) detailing isotopic purity, chemical assay, and trace metal content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry environment. For long-term storage, keep under inert atmosphere to minimize surface oxidation. Handle in accordance with good laboratory practices.
