Methyl cyclopentenolone

Methyl cyclopentenolone C화학적 특성, 용도, 생산

화학적 성질

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.
Cyclotene and its homologs are frequently used in flavor compositions for its caramel note, for example, in beverages and in confectionery.

화학적 성질

Off-white solid

출처

Reported to be found during the dry distillation of wood and in the corresponding tar oil. It has also been identified in fenugreek (FenaroWs Handbook of Flavor Ingredients, 1975).

용도

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.

제조 방법

By ketonic hydrolysis of the corresponding dicarboxylic ester (Arctander, 1969)

Toxicity evaluation

The acute oral LD50 value in guinea-pigs was reported as 1.4 g/kg (Dow Chemical Company, 1953) and that in rats as > 1.85 g/kg, while the acute dermal LD50 value in guinea-pigs exceeded 2 g/kg (Moreno, 1976). Methylcyclopentenolone was lethal to mice and rats at ip doses of 0.5-1 g/kg (Shugaev, 1959), and at a concentration of 7 χ 10-4 m was toxic to cultured human leucocytes (Withers, 1966).
