Properties
Pyrogallol has a unique chemical structure that makes it a potent reducing agent. It has three hydroxyl groups attached to a benzene ring, which gives it an acidic nature. It reacts vigorously with oxygen to produce a brownish-black precipitate, which makes it a useful indicator of oxygen presence in organic compounds. Pyrogallol has a melting point of 132°C and a boiling point of 377°C.
Reactions
Pyrogallol is used as a reducing agent in several chemical reactions. It can reduce metal ions such as silver and gold, and is used to develop photographic film. It also reduces oxidants such as ferric chloride and potassium permanganate. When pyrogallol comes in contact with oxygen, it forms a brownish-black color that indicates the presence of an oxidant.
Uses
Pyrogallol has several uses in different industries. In the chemical industry, it is used as a reducing agent and antioxidant. It is used as a developer in photographic film processing. Pyrogallol is also used in the production of dyes, tanning agents, and pharmaceuticals.
Pyrogallol has several applications in the biomedical industry. It has antioxidant properties that reduce oxidative stress in cells, which plays a role in aging and several diseases. Pyrogallol has also been shown to be effective in reducing the growth of cancer cells.
