Gallic Acid and Derivatives

Gallic Acid is a natural extracted substance from gallnuts, tea leaves and other plants. Gallic Acid is chemically identified as 3,4,5-trihydroxybenzoic acid.
Gallic Acid, with 3 hydroxy groups in its structure, performs as anti-oxidant and anti-corrosion agent. As Gallic Acid is a safe and environmentally friendly substance, it is used in many applications such as pharmaceutical, food, semiconductor chemicals and so on. We also supply the following derivatives of Gallic Acid.

  • Methyl Gallate
  • Ethyl Gallate
  • Propyl Gallate
  • Epicatechin Gallate
  • Epigallocatechin Gallate (EGCG)
  • Garocatechin Gallate (GCG)
  • Bismath Gallate
  • Pyrogallol
  • 2,3,4-Trihydroxybenzophenone
  • 2,3,4,4’-Tetrahydroxybenzophenone

Gallic Acid in Semiconductor industry

Gallic Acid acts as anti-corrosion agent in cleaning process of semiconductor productions. It requires high purity quality with very low existence of trace metals to avoid short-circuit. We supply high purity Gallic Acid EL grade (electronics grade) in 10-100 ppb range metals. Our factory is highly sophisticated in electronics industry with severe quality control systems based on Japanese semiconductor industry standard. We are ready to supply Gallic Acid EL grade from our inventory in Japan and USA.
