| Hazard Information | Back Directory | [Chemical Properties]
2,4-Dihydroxyacetophenone(89-84-9) appears as a yellow-brown to reddish-brown fine crystalline powder. It slowly decomposes in water and can dissolve in hot alcohol, pyridine, and glacial acetic acid. In contrast, it is nearly insoluble in ether, benzene, and chloroform. A reaction with iron chloride causes it to adopt a red hue. | [Uses]
2,4-Dihydroxyacetophenone is used as intermediate for pharmaceuticals.
| [Uses]
Reagent 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). | [Definition]
ChEBI: A dihydroxyacetophenone that is acetophenone carrying hydroxy substituents at positions 2' and 4'. | [Preparation]
Preparation 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 | [Synthesis]
2,4-Dihydroxyacetophenone is obtained by the acetylation of resorcinol and acetic acid. In addition, it can also be obtained by reacting resorcinol with chloroacetyl or acetic anhydride in the presence of zinc chloride. | [target]
Phospholipase (e.g. PLA) |
