Methyl cyclopentenolone Usage And Synthesis
- Chemical PropertiesOff-white solid
- Chemical PropertiesMethyl cyclopentenolone occurs in beechwood tar
and has a caramel-like (burnt sugar) odor. It has been identified as a flavor
component in food. Crystals of the compound usually contain 1 mol
of water. Synthetic routes of production are of limited importance in comparison
with isolation from beechwood tar. Homologs of cyclotene such as
3-ethyl-2-hydroxy-2-cyclopenten-1-one, C7H10O2, Mr 126.16,
2-hydroxy-3,4-dimethyl-2-cyclopenten-1-one, C7H10O2, Mr 126.16, and 2-hydroxy-3,5-dimethyl-2-cyclopenten-1-one, C7H10O2, Mr 126.16,
are also used as flavor ingredients and have similar caramel-like
Cyclotene and its homologs are frequently used in flavor compositions for its caramel note, for example, in beverages and in confectionery.
- UsesMethyl Cyclopentenolone is a flavoring agent that is a white crys- talline powder. it has a nutty odor suggesting a maple-licorice aroma when diluted. it is soluble in alcohol and propylene glycol, slightly soluble in most fixed oils, and sparingly soluble in water. it is obtained by synthesis. it is also termed 3-methyl-cyclopentane-1,2-dione.
