Description

Lutetium-175 is a stable, naturally occurring isotope of the rare earth element Lutetium, identified by CAS No. 14391-25-4. It is a critical material for advanced scientific and industrial applications due to its unique nuclear properties and high purity requirements. This isotope is essential for researchers and manufacturers in the fields of nuclear medicine, geochronology, and as a high-purity standard in analytical chemistry.

Application

• Nuclear Medicine & Radiopharmaceuticals: Used as a target material for the production of the therapeutic radioisotope Lutetium-177 (¹⁷⁷Lu), a key agent in targeted radionuclide therapy for cancers such as neuroendocrine tumors and prostate cancer.
• Scientific Research & Isotope Geochemistry: Serves as a stable isotope tracer in geological dating studies (Lu-Hf dating method) to understand the age and formation of rocks and planetary bodies.
• Neutron Activation Analysis (NAA): Employed as a flux monitor or comparator standard in NAA due to its well-characterized neutron capture cross-section, enabling precise elemental analysis.
• High-Purity Reference Standards: Utilized in the calibration of mass spectrometers and other analytical instruments to ensure accuracy in trace element and isotopic ratio measurements.
• Nuclear Reactor Studies: Acts as a burnable absorber or a spectral shield material in reactor design and neutron physics research due to its specific nuclear properties.

Quality Control

Our Lutetium-175 is produced and handled under stringent quality management systems. Each batch undergoes comprehensive analysis to verify isotopic enrichment, chemical purity, and radionuclidic purity where applicable. Certificates of Analysis (COA) are provided, detailing results from ICP-MS, GD-MS, and gamma spectroscopy. We support compliance with cGMP and other relevant regulatory frameworks for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its property of being easily oxidized, long-term storage under an inert atmosphere (e.g., argon) is recommended for optimal stability. Keep away from incompatible materials.
