Phosphotungstic Acid

Listing ID #779713

Phosphotungstic Acid has been also used to precipitate different types of dyes as "lakes", like basic dyes and triphenylmethane dyes, e.g. pararosaniline derivatives. Phosphotungstic Acid is used in histology for staining specimens, as a component of Phosphotungstic Acid Haematoxylin, PTAH, and “trichrome” reagents, and as a negative stain for imaging by a transmission electron microscope.
