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 ºC, boiling point 309 ºC, relative density 1.453, refractive index 1.561. Soluble in water, ethanol, ether, slightly soluble in benzene, chloro-form, carbon disulfide. When exposed to air, the color of the aqueous solution darkens, while the color of its caustic solution changes faster.

Used for preparing metal colloidal solution, coloring leather, dyeing and etching fur, hair, etc; It can also be used as a developer of film, an infrared photographic thermosensitive, a polymerization inhibitor of styrene and polystyrene, an intermediate of medicine and dyes, and an analytical reagent.

It is mainly used in the production of developer, polymerization inhibitor and infrared photographic thermosensitive. It is also used as an intermediate of medicine and dyes.

Used as analytical reagent, reductant and developer.

Used for analysis and determination of oxygen, antimony, bismuth, ce-rium, iron, molybdenum, tantalum and niobium; Used to absorb oxygen in gas analysis; Used for color reaction of nitrite, molybdenum, niobium, titanium, ce-rium, bismuth, copper, vanadium, iron, iodate, etc

Metal complexing agent.Gravimetric determination of bismuth and antimony. Reductants of gold, silver, mer-cury salts, phosphomolybdic acid and phosphotungstic acid, which are used to absorb oxygen in gas analysis.
