108-73-6 Usage


Phloroglucinol (1,3,5-trihydroxybenzene) is the core structure of a large family of substituted phenolics with broad, albeit weak, biological activity. Phloroglucinol is a useful metabolite for HPLC/DAD and bioassay dereplication.

Chemical Properties

white to light yellow crystal

Feature reaction of phloroglucinol

Reaction of formaldehyde with phloroglucinol under alkaline conditions generates orange compound. The colorimetric assay determination of this compound at the maximum absorption wavelength of 460 nm, can be used to detect low or trace formaldehyde in textile and garment.
Since phloroglucinol may occur enol and keto tautomers, it can react with ammonia according following reaction:
Under the influence of ammonia, 1,3,5-Benzenetriamine can be obtained by keto reaction of phloroglucinol
Under the influence of ammonia, 1,3,5-Benzenetriamine can be obtained by keto reaction of phloroglucinol, while this amine can also hydrolyze in aqueous acid to generate phloroglucinol. Besides phloroglucinol can also have enol reaction.
phloroglucinol can also have enol reaction

It can be used in verifications of antimony, arsenic, cerium, chromate, chromium, gold, iron, mercury, nitrites, osmium, palladium, tin, vanadium, vanillin and lignin, and measurement of furfural, pentose, pentosan, methanol, chloral hydrate, turpentine, Lignified cell tissues, free acid in gastric juice (HCl) and decalcified bone specimens. Besides it can also be used as biological reagent dyes.

Purification Methods

Crystallise the triol from water, and store it in the dark under nitrogen. [Beilstein 6 IV 7361.]


ChEBI: A benzenetriol with hydroxy groups at position 1, 3 and 5.


A potentially useful hygroscopic biochemical.



Production method

2,4,6-aminobenzoic acid can be obtained by 2,4,6-trinitrobenzoic acid`s reduction of zinc particles. After its dilute solution was heated at reflux for 20h, acidified with hydrochloric acid, cooled and crystallized, phloroglucinol can be obtained with a yield of 46-53%.
