Uranyl acetate dihydrate Uses
Uranium Oxyacetate (CAS NO.541-09-3) is used as a negative stain in electron microscopy. In fact, most procedures in electron microscopy for biology require the use of uranyl acetate. In the negative staining method 1 or 2% aqueous solution is normally being used. One of the most advantage of the type of staining is its simplicity, one can examine the sample within a few minutes after staining. Some biological samples may be adversely affected by uranyl acetate staining and, in these cases, a low voltage electron microscopy technique may be more suitable due to the improved resolution of low atomic number materials. 1% and 2% Uranyl Acetate solutions are used as an indicator, and a titrant in stronger concentrations in analytical chemistry, as it forms an insoluble salt with sodium (the vast majority of sodium salts are water-soluble). Uranyl Acetate solutions show evidence of being sensitive to light, especially UV and will precipitate if exposed. Uranyl Acetate is also used in a standard test—American Association of State Highway and Transportation Officials (AASHTO) Designation T 299—for alkali-silica reactivity in aggregates (crushed stone or gravel) being considered for use in cement concrete.

Uranyl acetate dihydrate Specification
Uranium Oxyacetate (CAS NO.541-09-3) is a yellow crystals with a slight odor of vinegar. It can soluble in water and reacting to give a milky solution. The reaction is not hazardous. It reacts weakly as an acid. Usually does not react as either oxidizing agents or reducing agents but such behavior is not impossible. May catalyze organic reactions. Inhalation of dust may irritate nose and throat. Contact with eyes causes irritation.
