2,4-Dihydroxyacetophenone Usage And Synthesis
  • Chemical Properties2,4-Dihydroxyacetophenone is yellow-brown to reddish-brown fine cryst. powder
  • Uses2,4-Dihydroxyacetophenone is used as intermediate for pharmaceuticals.
  • UsesReagent for iron as a 10% alcoholic solution. A red color is obtained with ferric ions in slightly acid solution: Cooper, Ind. Eng. Chem. Anal. Ed. 9, 334 (1937).
  • DefinitionChEBI: A dihydroxyacetophenone that is acetophenone carrying hydroxy substituents at positions 2' and 4'.
  • PreparationPreparation by reaction of acetic acid on resorcinol,
    with zinc chloride (Nencki reaction) (94%)
    with boron trifluoride
    with Amberlite IR-120 (a cation exchange resin, sulfonic acid type) (87%)
    with polyphosphoric acid (63%)
    with 70% perchloric acid (33%).
  • Synthesis Reference(s)Journal of the American Chemical Society, 70, p. 428, 1948 DOI: 10.1021/ja01181a521
  • Safety ProfileModerately toxic by ingestion. Experimental reproductive effects. A severe eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
