Description

Sodium Iodide (125 I) is a radioactive diagnostic agent where the iodine is the radioisotope Iodine-125. This compound is critical for precise medical imaging and therapeutic applications due to its specific gamma emission profile. It is primarily utilized in the nuclear medicine and pharmaceutical research sectors for diagnostic procedures and radiopharmaceutical development. Our supply ensures high specific activity and radiochemical purity to meet stringent clinical and research requirements.

Application

• Radiopharmaceutical Manufacturing: A key precursor in the synthesis of diagnostic and therapeutic agents labeled with Iodine-125.
• Medical Diagnostics: Used in radioimmunoassays (RIA) and other in vitro diagnostic tests for hormone and protein detection.
• Thyroid Function Studies: Employed in research and clinical settings to study iodine uptake and metabolism.
• Research & Development: Serves as a tracer in biochemical, pharmacological, and metabolic pathway research.
• Industrial Tracer Applications: Used in non-destructive testing and flow studies in controlled industrial environments.
• Calibration Source: Acts as a calibration standard for gamma counters and other radiation detection equipment.

Quality Control

Every batch of Sodium Iodide (125 I) is manufactured and tested under strict quality systems. We ensure compliance with relevant pharmacopeial standards for radioactive precursors where applicable. Key parameters including radiochemical purity, radionuclidic purity, specific activity, and sterility (for injectable grades) are rigorously controlled. Certificates of Analysis (COA) detailing all test results are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in appropriate shielded containers at room temperature (15-25°C) or as specified on the product label. Due to its hygroscopic nature, the product should be kept in a dry environment. All handling and storage must comply with local and international regulations for radioactive materials.
