Phloroglucinol is a reagent of the Tollens' test for pentoses. This test relies on reaction of the furfural with phloroglucinol to produce a colored compound with high molar absorptivity. [26] A solution of hydrochloric acid and phloroglucinol is also used for the detection of lignin (Wiesner test).
Phloroglucinol carboxylic acid is a trihydroxybenzoic acid, a type of phenolic acid. It is produced by Pseudomonas fluorescens . [ 1 ] It is a catechin degradation product excreted by the bacterium Acinetobacter calcoaceticus , a species of bacteria part of the human body normal flora, grown on catechin as sole source of carbon. [ 2 ]
2,4-Diacetylphloroglucinol or Phl [1] [2] is a natural phenol found in several bacteria: . Specific strains of the Gram-negative bacterium Pseudomonas fluorescens. [3] This compound is found to be responsible for the antiphytopathogenic [4] and biocontrol [5] properties in these strains.
2,4,6-Trihydroxyacetophenone (THAP) is a chemical compound that is a derivative of phloroglucinol. In an animal model, THAP was reported to enhance cholesterol 7 alpha-hydroxylase (CYP7A1) activity. [1]
The proteobacterium Pseudomonas fluorescens produces phloroglucinol, phloroglucinol carboxylic acid and diacetylphloroglucinol. [44] Another example of phenolics produced in proteobacteria is 3,5-dihydroxy-4-isopropyl-trans-stilbene, a bacterial stilbenoid produced in Photorhabdus bacterial symbionts of Heterorhabditis nematodes.

The synthesis of 2,4,6-Trihydroxyacetophenone (THAP) from phloroglucinol is representative: [1] If two-equivalents are added, 2,4-Diacetylphloroglucinol is the product. Hoesch reaction example, 1-(2,4,6-trihydroxyphenyl)ethanone from phloroglucinol. An imine can be isolated as an intermediate reaction product.
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.
