Description

Tetraphenylarsonium Oxotechnetiumbis(Ethanedithiolate) is a specialized organometallic complex containing technetium-99m, a key radioisotope in nuclear medicine. This compound is of significant value as a precursor or intermediate in the synthesis of radiopharmaceuticals for diagnostic imaging. It is primarily needed by research institutions, radiopharmaceutical manufacturers, and nuclear medicine departments developing targeted imaging agents for Single Photon Emission Computed Tomography (SPECT).

Application

• Precursor for the synthesis of technetium-99m (99mTc) based radiopharmaceuticals.
• Research and development of novel SPECT imaging agents for cardiac, renal, and tumor localization.
• Intermediate in the preparation of brain perfusion agents and other receptor-targeted diagnostic compounds.
• Chemical standard for analytical method development and quality control in radiopharmacy.
• Used in studies investigating coordination chemistry and redox properties of technetium complexes.
• Component in the kit formulation for instant technetium labeling of biomolecules.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for radiopharmaceutical precursors. Each batch is characterized to confirm identity, purity, and radiochemical purity where applicable. Certificates of Analysis (COA) detailing specific test results are available upon request. We adhere to strict quality management protocols suitable for research and development use.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as specified on the label. Due to its sensitivity, store under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Keep away from incompatible materials.
