Pyrogallol was first obtained in 1786 from gallic acid, obtainable from galls and barks of various trees. It is converted to pyrogallol by heating with water under pressure. ... Alkaline solutions of pyrogallol absorb oxygen efficiently and are used in determining the oxygen content of gas mixtures
