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 reaction makes use of phloroglucinol as nucleophile. Phlobaphenes formation (tannins condensation and precipitation) can be minimized in using strong nucleophiles, such as phloroglucinol, during pine tannins extraction. [24] Phloroglucinol is used in plant culture media. It demonstrates both cytokinin-like and auxin-like activity.
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 ...

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 U.S. Army Medical Center of Excellence (MEDCoE) is located at Fort Sam Houston, Joint Base San Antonio, Texas. MEDCoE comprises the 32d Medical Brigade, the U.S. Army Medical Professional Training Brigade (MPTB), and the AMEDD Noncommissioned Officers Academy (NCOA). It serves the U.S. Army in educating and training all of its medical ...
It is the symmetrically dimethylated derivative of pyrogallol. It is a colorless solid, although typical samples are brown owing to air-oxidized impurities. Together with guaiacol, syringol and its derivatives are produced by the pyrolysis of lignin. Specifically, syringol is derived from the thermal decomposition of the sinapyl alcohol component.
The San Antonio Market is one of 20 large military medical markets that directly report to the Defense Health Agency (DHA).
