Overview of Pyrogallol

 

Pyrogallol (also known as 1,2,3-trihydroxybenzene or pyrogallic acid) is a white to brownish crystalline solid, ahighly water-soluble phenolic compound sensitive to air oxidation.

Chemical Formulation: C6H6O3 C6H3(OH)3. Pyrogallol formula: Benzene-1,2,3-triol. Pyrog structures: Benzene ring with three adjacent hydroxyl groups. The color of the Pyrogallol is white when it's pure. It becomes brown after exposure to oxygen or air, including: a strong reducing agent, an antioxidant, and an oxygen absorber.

 

 

Application of Pyrogallol

 

Industrial and analytical Utilization

 

  • Pyrogallol utilizes: Oxygen is a gas analyzer's absorbent, as well as a reducing agent in photography, and dyes
  • Utilized in cosmetics, hair dyes, and also as a decomposition agent for metals

 

Chemical Synthesis

 

  • Pyrogallol is a precursor for antioxidants, inks, and specialty chemical compounds
  • Relative to estrifications that involve diethyl Oxalate as a component in certain condensation or reduction reactions

 

 

Safety and Handling Guideline

 

  • Protect yourself with goggles and gloves, and wear appropriate clothes
  • Avoid contact with skin for prolonged periods (can cause irritation or staining)
  • Only use in an area that is well ventilated and in a light-sensitive area.
  • Place in airtight, sealed containers to stop the oxidation
  • Use MSDS guidelines as well as standard safety procedures
