It is occasionally used as a 0.5% or 1% aqueous negative stain in transmission electron microscopy (TEM) because it shows a finer grain structure than uranyl acetate. However, uranyl formate does not easily go into solution, and once dissolved, has a rather limited lifetime as a stain. It is quite sensitive to light, especially ultraviolet light, and will precipitate if exposed. See also References - 2SPI.com, compound information, retrieved May 3, 2011.
