| Para Methoxy Acetophenone Usage And Synthesis |
Chemical Properties | white powder | Uses | p-Hydroxypropiophenone is a 4-hydroxyphenyl ketone used in the preparation of potential antitumor agents. p-Hydroxypropiophenone is a lignin degrradation product. | Uses | Intermediates of Liquid Crystals | Uses | gonadotropic hormone inhibitor | Preparation | Preparation by Fries rearrangement of phenyl propionate with aluminium chloride in refluxing carbon disulfide ? then at 130–150° for 2–3 h after solvent elimination (45–50%) with aluminium chloride in nitrobenzene at 50° for 18 h (72%) or at ? 20° for 48 h (60%) with aluminium chloride in nitromethane at 20° for 7–8 days (80%) with aluminium chloride in chlorobenzene using microwave irradiation for ? 3 min at 106° (62%) with aluminium chloride in ethylene dichloride at 95° for 5 h or in heptane at ? 80–90° for 7 h (36%), in benzene or in tetrachloroethane at 80°; with aluminium chloride in the presence of propionyl chloride at 50–60° for ? 6 h (49%) with aluminium chloride without solvent at 50° for 10 h with titanium tetrachloride in nitromethane at 20° for 7 days (56%) or ? without solvent at 50° for 10 h (39%) with polyphosphoric acid at 100° (61%) with boron trifluoride at 50° for 3 h (46%) with stannic chloride at 50° for 3 h (10%). | Definition | ChEBI: P-Hydroxypropiophenone is a member of acetophenones. | Synthesis Reference(s) | The Journal of Organic Chemistry, 30, p. 2491, 1965 DOI: 10.1021/jo01018a528 | Safety Profile | Poison by
intraperitoneal, subcutaneous, and parenteral
routes. An experimental teratogen. Other
experimental reproductive effects. A
flammable liquid. When heated to
decomposition it emits acrid smoke and
irritating fumes. See also KETONES. | target | Estrogen receptor | Purification Methods | 4'-Hydroxypropiophenone [70-70-2] M 150.2, m 149o, b 140-145o/0.5mm, 8.05. Crystallise the phenone from H2O (m 149.8-150.2o) or EtOH (m 147o). The benzoyl derivative has m 117o, and the semicarbazone has m 183o (EtOH). [Beilstein 8 H 102, 8 II 104, 8 III 379.] |
