    What Is Pyrogallol CAS 87-66-1?

    Pyrogallol CAS 87-66-1 is white odorless crystal. It tastes bitter. Exposure to air and light turns gray. Heat slowly and begin to sublimate. Melting point 133-134 ℃, boiling point 309 ℃, relative density 1.453, refractive index 1.561. Soluble in water, ethanol, ether, slightly soluble in benzene, chloroform, carbon disulfide. When exposed to air, the color of the aqueous solution darkens, while the color of its caustic solution changes faster.
