Description

Rhenium187 CAS NO 14391-29-8 is a stable, non-radioactive isotope of the rare transition metal rhenium. This high-purity isotope is critical for applications requiring precise atomic weight and isotopic purity, free from radioactive decay interference. It is essential for advanced research and development in fields such as geochemistry, materials science, and as a calibration standard in mass spectrometry.

Application

• Geochemical Tracers & Dating: Used in the Re-Os isotopic system for precise dating of geological samples, including meteorites, mantle rocks, and ore deposits.
• Mass Spectrometry Calibration: Serves as a primary isotopic standard for high-precision analytical instruments due to its stable and well-defined isotopic composition.
• Advanced Materials Research: Employed in the development and characterization of high-performance alloys, superalloys, and catalysts where isotopic purity is a study variable.
• Nuclear Medicine Precursor: Acts as a target material for the production of radioisotopes like Rhenium-186, used in therapeutic radiopharmaceuticals.
• Reference Standards: Used to prepare certified reference materials (CRMs) for quality control in analytical laboratories.
• Fundamental Physics Research: Utilized in studies of atomic properties, nuclear structure, and for testing fundamental physical constants.
