Description

Uranyl Acetate is a yellow, crystalline inorganic salt of uranium, widely recognized for its utility as a heavy metal stain and analytical reagent. Its primary commercial value lies in its ability to provide high-contrast imaging in electron microscopy and its role in various chemical synthesis and analytical procedures. This product is essential for laboratories and industrial facilities in the life sciences, materials research, and nuclear technology sectors seeking a reliable source of high-purity material.

Application

• Electron Microscopy Staining: A critical negative stain for enhancing contrast in biological specimens (e.g., viruses, proteins, DNA) and materials science samples viewed under transmission electron microscopes (TEM).
• Analytical Chemistry: Used as a reagent in gravimetric and volumetric analysis, particularly for the determination of phosphates, arsenates, and other anions.
• Nuclear Fuel Cycle Research: Serves as a precursor in the synthesis of other uranium compounds and in studies related to uranium chemistry and fuel processing.
• Photography & Ceramics: Historically used in photographic toning and as a colorant in specialty ceramics and glass, producing yellow to green hues.
• Catalysis: Investigated as a catalyst or catalyst precursor in certain organic synthesis reactions.
• Educational & Research: Employed in academic and institutional research settings for teaching and experimental purposes in inorganic and radiochemistry.

Quality Control

Our Uranyl Acetate is manufactured and tested under stringent quality management systems to ensure batch-to-batch consistency and reliability for sensitive applications like electron microscopy. Each lot is analyzed for key parameters including uranium content, purity, and the absence of interfering impurities. A comprehensive Certificate of Analysis (COA) detailing assay results, physical properties, and trace metal analysis is provided with every shipment to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to air or light may affect its stability and performance. Keep away from incompatible materials.
