Description

Germanium Hydroxide (68Ge(Oh)4), (T-4)- is a specialized inorganic compound of significant interest in advanced material science and nuclear chemistry. Its value lies in its role as a precursor for high-purity germanium oxides and as a source of the germanium-68 isotope, which is the parent nuclide for the important medical radioisotope gallium-68. This product is essential for researchers and manufacturers in the radiopharmaceutical, semiconductor, and specialty catalyst industries, where precise material properties and isotopic purity are critical.

Application

• Radiopharmaceutical Precursor: As the generator parent for Gallium-68 (68Ga), used in Positron Emission Tomography (PET) imaging agents.
• Semiconductor Research: A starting material for the synthesis of high-purity germanium dioxide (GeO2) used in fiber optics and infrared optical components.
• Catalyst Synthesis: Utilized in the preparation of specialized catalysts for polymerization and organic synthesis reactions.
• Analytical Chemistry: Serves as a standard or reagent in spectroscopic analysis and geochemical studies.
• Material Science: Used in the development of novel germanium-based nanomaterials and thin films.
• Nuclear Medicine Research: Key material in the development and calibration of 68Ge/68Ga generator systems.

Quality Control

Every batch of our Germanium Hydroxide is produced and controlled under a strict quality management system. Radiochemical purity, isotopic enrichment, and chemical assay are rigorously verified using advanced analytical techniques including gamma spectrometry, ICP-MS, and titration. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use to prevent moisture absorption and degradation.
