Applicazioni

Reagent for pentoses, pentosans and aldehydes. Used as a bone decalcifier in microscopy specimens.Phloroglucinol is mainly used as a coupling agent in printing. It is an active component of Tollen’s reagent and Gunzburg reagent used to test pentoses and hydrochloric acid in gastric juice respectively. In analytical chemistry, it is used to study condensed tannins by means of depolymerization. It is also involved in the synthesis of 2,4,6-triamino-1,3,5- trinitrobenzene, trinitrophloroglucinol and pharmaceuticals like flopropione .

Note

Incompatible with acid chlorides, acid anhydrides, bases and oxidizing agents.

Letteratura

Reacts with mono- or dimethylamine in DMF-water, with displacement of one of the OH groups, to give 5-aminoresorcinols: Helv. Chim. Acta, 56, 510 (1973).

The electron-rich nucleus undergoes acylation with nitriles under mild Lewis acid catalysis, to give ketones (Houben-Hoesch reaction).

Selective monobromination cannot be achieved conventionally. For bromination-debromination protocols for the preparation of the mono- and di-brominated derivatives, see: Can. J. Chem., 67, 335 (1989).
