Audited Supplier Rogallic Acid, also known as 1,2,3-Trihydroxybenzene, 1,2,3-Benzenetriol , Pyrogallic acid, Pyrogallol. At room temperature, it is a white shiny crystalline powder that tastes bitter and slowly turns dark gray when exposed to the air. Slow heating can sublimate. soluble in water. The aqueous solution gradually turns dark when exposed to air, and the caustic soda aqueous solution discolors quickly. Soluble in ethanol and ether, slightly soluble in benzene, chloroform, carbon disulfide. The pyrogallic acid is flammable. It is a toxic chemical and its toxicity is similar to that of phenol. It has a strong irritating effect on the skin, eyes and mucous membranes. Inhalation, skin contact and ingestion are harmful and can cause melanin deposition in the skin. Harmful to aquatic organisms, may cause long-term adverse effects on the aquatic environment and may have irreversible consequences. It is mainly used as raw materials and intermediates for chemical reagents, chemical and pharmaceuticals. The formula is C6H6O3.

Widely used in fine chemicals, used to synthesize new photosensitive materials, food
preservation, new drugs for treating cardiovascular and cerebrovascular diseases, new anti-tumor drugs, drugs for treating senile dementia, drugs for treating mental disorders, textile printing and dyeing, light industrialization, color printing plate making, micro Electronics industries, rare metal analysis, gas analysis, and photographic imaging industries absorb carbon monoxide.
1) The pyroic gallic acid is used as an analytical reagent and is used as an oxygen scavenger for gas analysis of coal gas, flue gas, coke gas, water gas, etc. It is an indispensable oxygen removal reagent for nitrogen fertilizer, cokemaking, smelting, and petrochemicals. It is used as a strong reducing agent in the analysis of gold, silver, and mercury salts; it is the best reagent for determining COD in wastewater under strong acid conditions. As an oxygen absorbent, pyrogallic acid can be used for food processing and food preservation to prevent food spoilage. In addition, synthetic resin antioxidants usually contain pyroic acid.
2) Pyrogallic acid can be used as a thermal sensitizer for infrared photography. The thermosensitive latex film is fixed on the film base, dried, and then coated with a layer of photosensitive silver chloride latex film with extremely low concentration. After the infrared exposure, the wet film development is not necessary, and a weak photograph can be displayed on the film. After heat treatment, the dark blue picture is finally displayed. This is a very important photography in national defense. The pyroic gallic acid is also a kind of developer. Its development speed is fast, and it is suitable for high temperature and high pH conditions. ;
3) Pyrogallic acid instead of phenol used in the manufacture of epoxy resin, its nature is more than ordinary epoxy resin;
4) Pyrogallic acid can be used as a polymerization inhibitor and antioxidant. For example, in the styrene-butadiene synthetic rubber as an antioxidant; in the neoprene vulcanizing agent by adding 0.5 to 1% coking gallic acid, can effectively prevent premature vulcanization; add 1.0 to 1.5% of the coke in the polyisoprene rubber Gallic acid can effectively inhibit the oxidative degradation of rubber and improve its processing performance;
5) Anti-fouling agent for PVC polymerization tanks. Before the polymerization reaction, use a cola-containing gallic acid alcohol solution at a dosage of 8.8 g/m to coat the inner wall of the kettle to dry it, which can reduce the PVC's knot on the inner wall of the kettle during the polymerization process. The amount of scale makes the inner wall of the polymerization tank bright as before;
For the preparation of metal colloidal solution, colored leather, fur, hair dyeing, etching; and can be
used as film developer, infrared photography thermosensitive agent, styrene and polystyrene block poly poly agent, medicine and dye intermediates and analysis reagent etc.. Pyrogallic acid used as oxygen absorber in gas analysis, in terms of cosmetics, hair, hair coloring agent for powder agent etc.
