Description:
Fourrine 85 or benzene-1,2,3-triol is a benzenetriol. It is a white crystalline powder and a powerful reducing agent. An alternate preparation is heating para-chlorophenoldisulphonic 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.
