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 .
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
