Trihydroxybenzenes

The trihydroxybenzenes (or benzenetriols) are organic compounds with the formula C₆H₃(OH)₃. Also classified as polyphenols, they feature three hydroxyl groups substituted onto a benzene ring. They are white solids with modest solubility in water.^[1]

Pyrogallol	Hydroxyquinol	Phloroglucinol
Benzene-1,2,3-triol	Benzene-1,2,4-triol	Benzene-1,3,5-triol

The enzyme pyrogallol hydroxytransferase uses benzene-1,2,3,5-tetrol and benzene-1,2,3-triol (pyrogallol), whereas its two products are benzene-1,3,5-triol (phloroglucinol) and benzene-1,2,3,5-tetrol. This enzyme can be found in Pelobacter acidigallici.^[2][3]
