2-Methyl butyric acid Usage And Synthesis
Description | 2-Methylbutyric acid has a pungent, acrid odor similar to Roquefort cheese with an acrid taste. At low dilutions, it has a pleasant fruity taste. May be prepared by decarboxylation of methyl ethyl malonic acid (with heat); also by oxidation of fermentation amyl alcohol (fusel oil). |

Chemical Properties | clear colorless to pale yellowish liquid |
Uses | Used in the synthesis of 2-methylbutyric anhydride |
Definition | ChEBI: A methylbutyric acid comprising a butyric acid core carrying a 2-methyl substituent. Produced from amino acid leucine during nutrient starvation in bacteria. |
Aroma threshold values | Detection: 10 to 60 ppb. Aroma characteristics at 1.0%: acidic sour, pungent, ripe fruit leather, lingon[1]berry, dirty cheesy, fermented pineapple fruity with a woody nuance |
Taste threshold values | Taste characteristics at 10 ppm: dirty, acidic sour, ripe fruity, with a dairy buttery and cheesy nuance |
