| | 2,5-Dimethoxytetrahydrofuran Usage And Synthesis |
| Chemical Properties | Colorless to light yellow liqui | | Uses | 2,5-Dimethoxytetrahydrofuran is a tetrahydrofuran derivative that finds application in proteomics research and in organic synthesis. It is also used as an intermediate for atropine sulfate, which is an anticholinergic drug. Further, it acts as a precursor of butanediol. In addition to this, it is used as a photographic hardener and as disinfectant in formulations. | | Synthesis | 2,5-Dimethoxytetrahydrofuran is prepared by catalytic hydrogenation of 2,5-dialkoxy-2,5-dihydrofurans.
| | Solubility in water | Practically insoluble in H2O; soluble in MeOH, Et2O, THF.
| | Precautions |
Flammable liquids must be stored in a cool, ventilated place. Noxious by inhalation, ingestion, or by contact with skin. Use in a fume hood.
