1,2,4,5-Tetrahydroxybenzene Structural Formula: CAS Registry Number: 642-96-6 634-94-6 636-32-8 All isomers share the molecular weight 142.11 g/mol and the chemical ...
The trihydroxybenzenes (or benzenetriols) are organic compounds with the formula C 6 H 3 (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.
It is a metabolite in the degradation of 3,4,5-trihydroxybenzoate (gallic acid) by Eubacterium oxidoreducens. [ 1 ] The enzyme pyrogallol hydroxytransferase uses 1,2,3,5-tetrahydroxybenzene and 1,2,3-trihydroxybenzene ( pyrogallol ), whereas its two products are 1,3,5-trihydroxybenzene ( phloroglucinol ) and 1,2,3,5-tetrahydroxybenzene.
Thus, the two substrates of this enzyme are 1,2,3,5-tetrahydroxybenzene and 1,2,3-trihydroxybenzene (pyrogallol), whereas its two products are 1,3,5-trihydroxybenzene (phloroglucinol) and 1,2,3,5-tetrahydroxybenzene. This enzyme participates in benzoic acid degradation via CoA ligation.
The enzyme pyrogallol hydroxytransferase uses 1,2,3,5-tetrahydroxybenzene and 1,2,3-trihydroxybenzene (pyrogallol) to produce 1,3,5-trihydroxybenzene (phloroglucinol) and 1,2,3,5-tetrahydroxybenzene. It is found in the bacterium species Pelobacter acidigallici .
In a human study 16.4 to 41.6% of retained benzene was eliminated through the lungs within five to seven hours after a two- to three-hour exposure to 47 to 110 ppm and only 0.07 to 0.2% of the remaining benzene was excreted unchanged in the urine.

The 3 substrates of this enzyme are 2-hydroxy-1,4-benzoquinone, NADH, and H +, whereas its two products are 1,2,4-trihydroxybenzene and NAD +. This enzyme participates in gamma-hexachlorocyclohexane degradation and 1,4-dichlorobenzene degradation .
