Applications

Pyrogallol is used in hair dying and suturing materials dying. It is used as a developing agent in black and white developers, as a metal-complexing agent and is involved in oxygen absorption in gas analysis. It exhibits antiseptic properties. Its alkaline solution is used to absorb oxygen from air, thereby it plays a vital role to calculate the amount of oxygen in air.

Notes

Air and light sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, alkalis, metal oxides, ammonia, iodine, lime water, potassium permanganate and strong bases.
