Project at a Glance	Contents on the CD ROM
Pyrogallol or benzene-1,2,3-triol is a benzenetriol. It is a white crystalline powder and a powerful reducing agent. It was first prepared by Scheele 1786 by heating gallic acid. An alternate preparation is heating para-chlorophenol disulphonic acid with potassium hydroxide. When in alkaline solution, it absorbs oxygen from the air, turning purple from a colourless solution. It can be used in this way to calculate the amount of oxygen in air, notably via the use of the Orsat apparatus. One can find its uses in hair dying, dying of suturing materials and for oxygen absorption in gas analysis. It also has antiseptic properties. Pyrogallol was also used as a developing agent in black-and-white developers, but its use is largely historical except for special purpose applications. Hydroquinone is more commonly used today.Though a popular photographic developing agent in the 19th and early 20th centuries, pyrogallol largely fell out of favor around the 1920s, though still used by a few notable photographers including Edward Weston. Pyrogallol was tested in two independent bacterial mutation studies; both studies gave positive results in one or more strains of S. typhimurium or E. coli. The current main commercial application of pyrogallol is the production of pharmaceuticals and pesticides. In analytical chemistry, pyrogallol is used as a complexing agent, reducing agent, and, in alkaline solution, as an indicator of gaseous oxygen. Pyrogallol was nominated for testing by private individuals based on its frequent occurrence in natural and manufactured products, including hair dyes, and the apparent lack of carcinogenicity data.
