Pyrogallol was also used as a developing agent in the 19th and early 20th centuries in black-and-white developers. Hydroquinone is more commonly used today. Its use is largely historical except for special purpose applications. It was still used by a few notable photographers including Edward Weston. In those days it had a reputation for ...
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 .
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.

In enzymology, a pyrogallol 1,2-oxygenase (EC 1.13.11.35) is an enzyme that catalyzes the chemical reaction. 1,2,3-trihydroxybenzene + O 2 ...
By reacting the bromopyrogallol red with niobium(V) in a tartrate medium at pH 6.0, an intense blue coloured 3:1 reagent was formed. The sensitivity and conditional selectivity of bromopyrogallol red was also studied and results show that trace amounts of silver can be detected from the formation of a ternary complex between 1,10-phenanthroline, bromopyrogallol red and silver ion.
