Pyrogallol Usage And Synthesis

Chemical Properties	white crystalline solid
Chemical Properties	White or nearly white needle- or leaf-shaped crystals or crystalline powder.Pyrogallol is practically odorless.
Uses	Pyrogallol is used in the manufacture of various dyes; in dyeing furs, hairs, and feathers; for staining leather; in engraving;as a developer in photography; and as an analytical reagent..
Uses	Metal-complexing agent
Uses	Complexing agent; reducing agent; alkaline solution indicator for gaseous oxygen.
Definition	ChEBI: A benzenetriol carrying hydroxy groups at positions 1, 2 and 3.
Production Methods	Pyrogallol is prepared by heating dried gallic acid at about 200°C with the loss of carbon dioxide or by the chlorination of cyclohexanol to tetrachlorocyclohexanone, followed by hydrolysis.
General Description	Odorless white to gray solid. Sinks and mixes with water.
Air & Water Reactions	Turns gray on exposure to light or air. Water soluble.
Reactivity Profile	Pyrogallol is a strong reducing agent. Reacts with alkalis, NH3, antipyrine, camphor, phnol, iron and lead salts, iodine, lime water, menthol and KMnO4.
Hazard	Toxic by ingestion and skin absorption.
Health Hazard	The toxic symptoms are similar to those of pheol. It can enter the body by absorption through skin and ingestion. The poisoning effects are nausea, vomiting, gastritis, hemolysis, methemoglobinemia, kidney and liver damage, convulsions, and congestion of lungs. High doses can cause death. Ingestion of 2-3 g of solid can be fatal to humans. The LD50 values varied widely in species. The oral LD50 value in mice is about 300 mg/kg.
Health Hazard	Inhalation of dust causes irritation of nose and throat. Ingestion may cause severe gastrointestinal irritation, convulsions, circulatory collapse, and death. Contact with eyes causes irritation. Skin contact can cause local discoloration, irritation, eczema, and death; repeated contact can cause sensitization.
Fire Hazard	Pyrogallol is probably combustible.
Contact allergens	Pyrogallol belongs to the phnols group. It is an old photograph developer and a low sensitizer in hair dyes.
Safety Profile	Human poison by ingestion and subcutaneous routes. An experimental poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. 1 198 PPRSOO PYROSULFURYL CHLORIDE Readdy absorbed through the skin. Human systemic effects by ingestion: convulsions, dyspnea, gastrointestinal effects. A severe skin and eye irritant. Incompatible with alkalies, NH3, antipyrine, penol, iron and lead salts, iodine, KMn04. When heated to decomposition it emits acrid smoke and irritating fumes. Used as a topical antibacterial agent, as an intermediate, hair dye component, and analytical reagent.
Carcinogenicity	Pyrogallol was not carcinogenic in mouse and rabbit chronic dermal studies. Mice were treated twice weekly with pyrogallol in actone (50%) on the shaved flank for life. There was no increase in dermal or systemic tumors. A similar study in rabbits also revealed no skin tumors, although positive controls showed an increase in tumors in both mice and rabbits. Pyrogallol was considered to be cocarcinogenic when administered dermally three times a week together with the skin carcinogen benzo[a]pyrene for 440 days; pyrogallol administered alone caused no increase in skin tumors.
