Description

Uranyl Acetate Dihydrate is a yellow, crystalline inorganic salt of uranium, widely recognized as a critical reagent in electron microscopy and analytical chemistry. Its primary value lies in its exceptional utility as a heavy metal stain for enhancing contrast in biological and materials science imaging. This high-purity compound is essential for research laboratories, quality control facilities, and industrial R&D departments operating in life sciences, nanotechnology, and nuclear chemistry. We supply consistent, high-grade material to support precise and reliable scientific outcomes.

Application

• Electron Microscopy Staining: Primary application as a negative stain for viruses, bacteria, and cellular structures in transmission electron microscopy (TEM).
• Analytical Chemistry: Used as a standard or reagent in quantitative analysis, including gravimetric and titrimetric methods for phosphate and other anions.
• Nuclear Fuel Cycle Research: Serves as a precursor in uranium chemistry studies and the synthesis of other uranium compounds.
• Ceramics & Pigments: Acts as a component in the production of specialized ceramics and uranium-based yellow pigments.
• Photography & Photochemistry: Historically used in photographic toning processes and in certain photochemical applications.
• Catalysis Research: Investigated as a catalyst or catalyst precursor in specific organic synthesis reactions.

Quality Control

Our Uranyl Acetate Dihydrate is manufactured under strict quality protocols to ensure high chemical purity and batch-to-batch consistency, suitable for sensitive analytical and research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, impurity profiles (including other metal ions), and physical characteristics. We adhere to relevant industry standards for laboratory reagents, and custom purity grades or specifications can be developed to meet specific project requirements.

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; therefore, containers must be kept tightly sealed after use to prevent degradation and absorption of atmospheric moisture. Keep away from incompatible materials.
