Uses

Pyrogallol (CAS NO.87-66-1) can be used in hair dying, dying of suturing materials and for oxygen absorption in gas analysis. but pyrogallol is not likely to be used as a modern hair dye due to the suspected toxicity of the compound.It also has antiseptic properties. It was also used as a developing agent in black-and-white developers, but its use is largely historical except for special purpose applications. 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.
