Phloroglucinol dihydrate is utilized in the preparation of active pharmaceutical ingredients such as flopropione. It acts as a reagent for the Tollens test for pentoses. It is mixed with hydrochloric acid and plays an important role for the detection of lignin (Wiesner test). It is involved in the analysis and qualitative detection of free hydrochloric acid in gastric juice by using Gunzburg reagent. Further, it serves as a coupling agent in printing. It is also employed as a reagent for pentoses, pentosans, aldehydes and as a decalcifier of bone specimens in microscopy.
