What is Pyrogallol?
Pyrogallol is a white glossy crystalline powder that is soluble in 2 parts water, 1 part ethanol, or 2 parts ether.Pyrogallol has a bitter taste. Exposed to air and light, Pyrogallol turns gray. Slowly heat up and begin to sublime. Melting point 133-134 ℃, boiling point 309 ℃, relative density 1.453. When exposed to air, the color of the aqueous solution darkens, while its alkaline solution changes color faster.
