Description

Indium-113 is a stable, non-radioactive isotope of the rare metal indium, identified by CAS No. 14885-78-0. It serves as a critical precursor material for the production of the medical radioisotope Indium-111, which is essential for diagnostic nuclear medicine imaging. This high-purity isotope is primarily required by radiopharmaceutical manufacturers, research institutions, and advanced material science laboratories developing specialized targets and tracers.

Application

• Radiopharmaceutical Precursor: Primary use as the target material for cyclotron production of the diagnostic imaging agent Indium-111.
• Nuclear Medicine Research: Used in the development and calibration of new radiopharmaceuticals and imaging protocols.
• Isotopic Tracer Studies: Employed in geological, environmental, and material science research as a stable isotopic tracer.
• High-Purity Target Manufacturing: Fabrication of specialized targets for nuclear reaction studies and isotope production.
• Reference Standard: Serves as a certified reference material for mass spectrometry and isotopic analysis.
• Advanced Alloys & Semiconductors: Used in trace amounts for doping and property modification in specialized electronic and semiconductor materials.

Quality Control

Our Indium-113 is produced and handled under strict quality management systems to ensure the highest isotopic and chemical purity required for sensitive applications like radiopharmaceutical manufacturing. Each batch is characterized for isotopic abundance (typically >99.9% 113In) and trace metallic impurities via high-resolution techniques including Glow Discharge Mass Spectrometry (GDMS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). A comprehensive Certificate of Analysis (COA) detailing isotopic purity, chemical assay, and impurity profile is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Keep the container sealed to minimize exposure to atmospheric contaminants. For long-term storage of high-purity material, an inert atmosphere (argon or nitrogen) is recommended to prevent surface oxidation.
