Phosphomolybdic acid, also known as dodeca molybdophosphoric acid or PMA, is a yellow-green chemical compound that is freely soluble in water and polar organic solvents such as ethanol.
P 1737 (OTTO) Phosphomolybdic acid, GR Cas 51429-74-4 - used as a stain in histology and in organic synthesis. P 1737 (OTTO) Phosphomolybdic acid, GR Cas 51429-74-4 - used as a reagent in thin layer chromatography (TLC) for staining phenolics, hydrocarbon waxes, alkaloids and steroids. It is freely soluble in water and polar organic solvents such as ethanol. Conjugated, unsaturated compounds reduce PMA to molybdenum blue.
