Chemical Properties |
Methyl
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
properties. |

Uses |
Methyl 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. |
